Featuring a thermal magnetic trip and advanced magnetic arc extinguishing, it safeguards solar PV and other DC power systems from overloads and short circuits. Its DIN rail mount and screw clamp wiring ensure fast, secure installation, making it an essential upgrade for professional-grade solar and DC power management. ## Description Product description Chtaixi DC Miniature Circuit Breaker Warm Tips Pay attention to polarity. Select wire size according to rated current. Magnetic Arc Extinguishing AC has a zero-crossing point, but DC does not, so DC arc is more difficult to extinguish than AC arc, which is why AC circuit breakers can not be used for DC power, and DC circuit breakers can be used for AC power. This DC mini circuit breaker is equipped with a magnetic field system under the breaking contacts, which can pull the arc to the arc extinguishing chamber to assist arc extinguishing. Quality Products to Protect Your Electricity Safety Polarity Marked This DC MCB has no polarity requirement in use, and the positive and negative poles can be inverted. However, the installation, use, and maintenance of DC circuits are based on polarity requirements. So, in order to provide reliable indication and reference for the distribution, we highly recommend that you connect the wires according to the marked polarity. Tunnel Terminal The clamping design of the terminal block is designed to connect firmly, and the tightening torque is 2.5 N.m. ( Soft silicone wire needs to crimp fixed the wire end with copper crimp before wiring. ) Make sure that the wires are tightly connected when connecting to prevent loosening and heating. The surface of the terminal is tin-plated, and the plating layer can improve conductivity, corrosion resistance, and durability. Silver Alloy Contacts Contacts are very important to circuit breakers, especially for DC distribution with high arc extinguishing requirements. Good contacts can reduce the heat generated by arcing during disconnection and reduce the wear of the contacts. This DC circuit breaker uses silver alloy contacts, which improves electrical durability, and protects your electricity safety for a long time. Specifications Installation DIN Rail Install the 35mm DIN rail horizontally in a stable environment. Hang the circuit breaker slot on the DIN rail Push the lower end of the circuit breaker into the DIN rail Dismounting Push the circuit breaker upward Turn the upper end of the circuit breaker out of the DIN rail Review: easy to use and install - Using these for compartmentalizing my solar inverter system in the new shed. separating the solar arrays, and then the battery from the power inverter. I like the rail that comes with the unit so it can be mounted however you wish. Review: Perfect for myapplication - I purchased this circuit breaker for my 5th wheel travel trailer. For some strange reason, the manufacturer didn’t think it was necessary to be able to disconnect the solar panel. This product worked well for my application. I went with the 50 amp breaker to allow for future upgrade. I am very happy with this product and would recommend it to others. ## Features - FUNCTIONS: Used to protect power distribution facilities from overload and short-circuit damage, and can also be used for control and isolation. - FAST TRIP: The electromagnetic trip system can trip immediately when the circuit is short-circuited to protect the safety of the circuit. - ARC EXTINGUISHING: DC arc extinguishing is more difficult than AC. This DC mini circuit breaker has a magnetic system to assist arc extinguishing. - APPLICATION: Used in DC power system, ship electric power system, solar photovoltaic system, or other DC system. - INSTALLATION: Screw clamp wires, 35mm DIN rail mount. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B09BQPC7L7 | | Best Sellers Rank | #11,347 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #4 in Miniature Circuit Breakers | | Brand | CHTAIXI | | Brand Name | CHTAIXI | | Circuit Breaker Type | Standard | | Current Rating | 50 Amps | | Customer Reviews | 4.5 out of 5 stars 118 Reviews | | Item Dimensions D x W x H | 2.95"D x 1.42"W x 3.15"H | | Item Weight | 6.35 Ounces | | Manufacturer | CHTAIXI | | Model | DZ47Z-63 | | Mounting Type | DIN Rail Mount | | Number Of Poles | 2 | | Number of Poles | 2 | | Part Number | 47Z63-2P1000 | | Product Dimensions | 2.95"D x 1.42"W x 3.15"H | | Voltage | 1000 Volts | ## Product Details - **Brand:** CHTAIXI - **Circuit Breaker Type:** Standard - **Current Rating:** 50 Amps - **Mounting Type:** DIN Rail Mount - **Product Dimensions:** 2.95"D x 1.42"W x 3.15"H ## Images ![DC Miniature Circuit Breaker, 2 Pole 1000V 50 Amp - Image 1](https://m.media-amazon.com/images/I/614m82le-4L.jpg) ![DC Miniature Circuit Breaker, 2 Pole 1000V 50 Amp - Image 2](https://m.media-amazon.com/images/I/51vBlz4lZoS.jpg) ![DC Miniature Circuit Breaker, 2 Pole 1000V 50 Amp - Image 3](https://m.media-amazon.com/images/I/516SF8QaIaL.jpg) ![DC Miniature Circuit Breaker, 2 Pole 1000V 50 Amp - Image 4](https://m.media-amazon.com/images/I/617q+Wx4OZL.jpg) ![DC Miniature Circuit Breaker, 2 Pole 1000V 50 Amp - Image 5](https://m.media-amazon.com/images/I/516E6P4zieL.jpg) ## Available Options This product comes in different **Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ easy to use and install *by P***K on October 18, 2023* Using these for compartmentalizing my solar inverter system in the new shed. separating the solar arrays, and then the battery from the power inverter.
