ED43B015 - 15Amp Circuit Breaker

ED43B015 - 15Amp Circuit Breaker

Need a dependable circuit breaker that fits seamlessly into your existing electrical system? The Siemens ED43B015 is a 15 Amp, 3-pole molded case circuit breaker designed to provide reliable overcurrent protection for commercial and industrial applications. As part of the trusted Siemens Sentron ED frame family, it serves as a form, fit, and functional replacement for compatible Siemens ED-frame installations, helping simplify maintenance while preserving compatibility with your existing equipment.

Designed with everyday performance in mind, the ED43B015 features a thermal magnetic trip unit that helps protect electrical systems from both overloads and short circuits. Its inverse-time thermal protection responds to prolonged overcurrent conditions, while the magnetic trip mechanism reacts quickly during short-circuit events.
