HED41B040L - 40Amp Circuit Breaker

HED41B040L - 40Amp Circuit Breaker

The Siemens HED41B040L is a 40 Amp, one-pole thermal magnetic circuit breaker used in Siemens SENTRON low voltage molded case circuit breaker systems with the ED frame configuration. This model is typically selected when replacing an existing breaker and the goal is to keep the original electrical setup intact. Matching the correct frame, amp rating, voltage, and lug arrangement is an important part of any breaker replacement, and this unit is built around those existing system requirements.
