ED43B030 - 30Amp Circuit Breaker

ED43B030 - 30Amp Circuit Breaker

If you need a circuit breaker that matches your existing Siemens electrical distribution equipment, the Siemens ED43B030 is a dependable choice. This 30 Amp, 3-pole molded case circuit breaker is designed for commercial and industrial applications where maintaining the original form, fit, and function is important. As part of the Siemens Sentron ED frame family, it serves as a compatible replacement for existing ED-frame installations while providing dependable overcurrent protection for properly matched systems.

The ED43B030 features a thermal magnetic trip unit that helps protect electrical circuits from both overloads and short circuits. The thermal element responds to prolonged overcurrent conditions, while the magnetic element reacts quickly during higher fault events.
