HED41B040 - 40Amp Circuit Breaker Description
HED41B040 - 40Amp Circuit Breaker
The Siemens HED41B040 is a 40 Amp, one-pole thermal magnetic circuit breaker used in Siemens SENTRON low voltage molded case circuit breaker systems with an ED frame. This breaker is a common choice for maintenance and replacement work when your existing installation requires the same breaker style and electrical specifications. Matching the frame, amperage, voltage, and terminal arrangement is important when working with installed equipment, and the HED41B040 is built to fit compatible systems without changing your original setup.
