CMB-043-27G6N-W-A Description

Short technical summary and product information.

CMB-043-27G6N-W-A is a single-pole thermal circuit breaker from Littelfuse. It is rated for 4A at 250V and uses a push-to-reset actuator. The breaker is non-illuminated and designed for panel-mount installation.

 

As a thermal breaker, it provides overcurrent protection in electrical circuits. The single-pole configuration supports one protected circuit, and the push-to-reset actuator allows manual reset after a trip. The panel-mount package is suited for fixed installation in equipment enclosures.

 

Approval markings include CE, cUL, TUV, UL1077, and UL1500. These approvals indicate the breaker has been evaluated to recognized standards for circuit protection components.
