## Overview

The Siemens QSA2020SPD is a 20-amp whole house surge protection device designed exclusively for Siemens panels. It integrates two single-pole breakers while occupying only two breaker spaces, delivering comprehensive surge protection across the entire electrical panel and all branch circuits. Featuring a 240V initial clamping level, robust 40,000A peak current rating, and 360/720 Joules transient energy capacity, it safeguards sensitive electronics from damaging voltage spikes. Built-in LED indicators provide real-time protection status, ensuring peace of mind with every flicker.

## Description

Product Description Siemens SPD device provides whole house surge protection. This device takes up the space of two standard single pole breakers, but also includes two single pole breakers so you do not lose any space in your Load Center. Once connected in the panel, the SPD device protects the entire panel and all branch circuits from surges, not just the two circuits connected to the SPD. Initial clamping level is 240 Volts. LED's provide protection status notification. Siemens strongly recommends against the use of "used" breakers. The installation of used breakers in a Siemens panel will void the warranty on the panel. Siemens does not sell used breakers and has not approved any 3rd party sellers to do so. desertcart.com In today's electronic world, your home's electrical, phone and cable systems are incomplete unless they incorporate surge protection. Since most everything in the home is microelectronic based, it is not practical to solely rely on surge protected plug strips. By installing this Siemens circuit breaker and surge protective device (SPD) in the load center of your home, surge protection is provided for all branch circuits. This version (model QSA2020SPD) is rated at 20 amps, and it's also available in a 15 amp version.The 20 amp QSA2020SPD surge protection device (view larger). The QSA2020SPD features a highly effective TVSS integrated with two 1-pole circuit breakers and incorporates the robust features of a secondary circuit breaker surge arrester with a lower clamping voltage ratings. Once connected in the panel, the SPD device protects the entire panel and all branch circuits from surges, not just the two circuits connected to the SPD. Two green LEDs provide protection status notification, and the device will notify you of any loss of surge protection by tripping one or both of the circuit breakers. These breakers should be used for circuit protection of frequently used household or facility circuits as the lights and devices connected to these circuits provide an effective indication that surge protection is being provided. All Type QP circuit breakers and SPD are plug-on style, with load terminals provided. The devices are rated for 120/240V AC and are calibrated for 40 degrees C maximum ambient applications.Surge Protective DevicesTo effectively surge protect your appliances and other sensitive electronic equipment, you need to stop surges before they get into your home and also control surges generated inside your home. Damaging surges enter your home primarily through the main utility power source, coax and telephone services. When left unprotected, surges will permeate throughout the home damaging electronics and appliances.What is a surge?A surge, sometimes called a transient or a spike, is a brief burst of energy (voltage and current). The most damaging surges enter through your home's power, cable and telephone lines. However, the majority of surges originate within the home from the action of motor based appliances like dishwashers, refrigerators, garage door openers, etc.How do surges affect my equipment?Large surges can damage equipment by "burning up" the internal components of your sensitive electronic equipment and appliances. Moderate surges disrupt equipment operation and damage internal components. Lower energy surges degrade equipment, which is referred to in the industry as "electronic rust."Why do you need this type of surge protection?The only way to surge protect microelectronic based appliances is through the application of an incoming service entrance surge protector like a Siemens SPD.QSA2020SPD Specifications Amperage 20 amps Number of Poles Two 1-pole circuit breakers Initial Clamping Level 240 volts Transient Energy Rating 360 Joules line-to-neutral 720 Joules line-to-line Transient Suppression 500 volts peak, line-to-neutral Voltage Rating 1000 volts peak, line-to-line Peak Current Rating (impulse) 40,000 amperes Discharge Voltage Characteristic @ 1,500A, 600 volts @ 5,000A, 800 volts (both line-to-neutral) Discharge Current Withstand Rating 10,000 amperes (line-to-neutral) Circuit Breaker Interrupting Rating 10,000A, 120/240V AC Listings/Certifications UL, CSA; meets UL 1449 3rd Edition QSA2020SPD Whole House Surge ProtectionAt a GlanceTwo 20 amp circuit breakersProvides whole house surge protectionTakes up the space of two standard single pole breakers, but also includes two single pole breakersInitial clamping level is 240 voltsHandy LED lights provide protection status notification Protect your home from electrical surges.

Review: Good Product - very easy installation i like it..
Review: Great easy addon at a low price - This is a great solution for adding surge protection without a lot of hassle or added expense. It fit our new Murray panel perfectly. (Murray is a Siemens product) There have been reviews questioning the effectiveness of this product which are simply unfounded. There have also been posts suggesting this product requires a grounded neutral bar in the box, this too is inaccurate. For anyone trying to install this product in anything but a Murray or Siemens panel forget about the warranty (whether it fits or not). The specific data sheet for this product directly states that this surge protector dumps surges across the hot and neutral wires. It says nothing about a ground wire anywhere. Also don't expect this device to protect all you equipment form every possible surge, you should always use an extra surge protector for you sensitive devices. Here is a bit more info on how products like this work and why those people saying it won't work are wrong. Inside the product is a "varistor" (it says so on the product data sheet) that is connected directly from the Hot bars(there are 2 of them) in the panel to the Neutral bar in the panel. A varistor resists all electrical flow below a specific threshold usually measured in voltage. Above that threshold (120 volts for this device) electricity starts to flow through the varistor increasing exponentially as the voltage goes up. This effectively short circuits electricity coming from any surge (usually this is from devices inside the house like washing machines ) from the hot to the neutral. Since electricity takes the path of least resistance that surge will dump back out onto the grid (unless there has been some catastrophe inside the home or something is wired wrong). Code requires panels that do not have a grounded neutral to have a separate ground wire back to the main shutoff panel where the neutral and ground are tied together so any surge coming from a grounded wire has to go back to the main panel and come into the protected panel through the neutral wire where it will be dumped onto the hot thus protecting the circuits.

## Questions & Answers

**Q: I have this installed but the (red) LEDs are off/dim. Does this need to be replaced? It is approximately 12 years old.**
A: If one or two LEDs are out that indicates the breaker is no longer working and the circuits they supply must not be hot (useable).  Check the two breakers with a voltage tester to be sure.  Being in service for 12 years circuits may have seen the voltage spike and tripped the breaker.  If they had been installed properly these two circuits would have fed voltage/current to circuits that were in use.

**Q: Does this offer the same level of protection as the SF100? One review said that the SF100 protected the "sensitive electronics" better.**
A: The Seimens protects nothing. I know personally. I had a lightning strike and lost $20,000.00 worth of Electronic equipment TV's, computers, printers and a multitude of other appliances. the Siemens unit was still glowing green as nothing had happened. When I contacted Siemens about their warranty I was informed it would only cover the wiring in the walls if it was damaged and nothing that was plugged into the outlets. Don't waste your money, they don't work at all and their warranty is very misleading.

**Q: Will this fit an ITE panel?**
A: Perfect fit in ITE EQ panel.

**Q: Can a load be connected to this protection device, such as a clothes dryer or does this need nothing attached?**
A: Yes a load can be connected to the unit and it is designed for that.  My understanding is not a double hot leg (220-240 volts) only 2 separate single leg loads (120 volts).  There are 20 amp and 15 amp versions available as I recall.  In short you check on your panel that you have 2 single breakers either 15 or 20 that are next to one another (or can be placed next to one another) and replace them with this unit.
