AA1-B0-42-410-1D1-C Description

Short technical summary and product information.

Littelfuse AA1-B0-42-410-1D1-C is a one-pole circuit breaker from the Circuit Breakers category. It is rated for 1A nominal current and 277V voltage. The breaker uses a magnetic hydraulic-delay mechanism to provide overcurrent protection.

 

This panel-mount unit is operated by a lever actuator and has no illumination. The single-pole configuration supports protection of one branch circuit or load. The magnetic hydraulic-delay design provides time-delayed overcurrent response.

 

The rated values of 1A and 277V define the operating envelope of the breaker. Panel mounting allows installation in control panels and equipment enclosures. The lever actuator provides manual switching and reset capability.
