HED43B020 - 20Amp Circuit Breaker Description
HED43B020 - 20Amp Circuit Breaker
The Siemens HED43B020 is a 20 Amp, 3-pole molded case circuit breaker from the SENTRON ED frame product line, designed for use in 480VAC electrical distribution systems. Featuring a thermal-magnetic trip unit, it provides protection against overloads and short circuits while delivering a 42kA interrupting capacity at 480VAC for applications where higher available fault current ratings are required. Whether you're replacing an existing breaker as part of routine maintenance or maintaining spare inventory for compatible equipment, this model is designed to provide the same form, fit, and function as the original Siemens device.
