Many others do not have this design.** A: Westinghouse Miniature Circuit Breakers are certified UL-489 which means suitable for branch circuit protection. The extended barriers are necessary for UL-489 approval. Other MCBs without the extended barriers are either NOT UL certified, or only UL approved as supplementary protectors meaning the MCB must be used with a fully rated breaker within the same panel. Applying Westinghouse MCBs will assure that your installation is utilizing fully UL approved breakers. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sn/products/512080106-westinghouse-ul-489-ac-miniature-circuit-breaker-30-amp-single](https://www.desertcart.sn/products/512080106-westinghouse-ul-489-ac-miniature-circuit-breaker-30-amp-single) --- *Product available on Desertcart Senegal* *Store origin: SN* *Last updated: 2026-06-20*
