MDT150 - 150 Amp Circuit Breaker

MDT150 - 150 Amp Circuit Breaker

The MDT150 circuit breaker delivers dependable, high‑capacity protection for both residential and commercial electrical systems. Engineered to handle the demands of modern electrical installations, this breaker supports 120/240 V service with a strong 150‑amp rating — making it ideal for load‑center mains, feeders, and large branch circuits. Its double‑pole configuration ensures steady, even power distribution across both hot legs while guarding against overloads or short circuits. Thanks to a 10 kA interrupt capacity, the MDT150 reliably interrupts fault currents before they can damage wiring or connected equipment. Compact enough to fit into most panel boards, yet powerful enough to serve demanding applications, this circuit breaker is a smart choice when you want consistent, long-term performance and enhanced safety.
