AA1-B2-12-615-2D1-C Description

Short technical summary and product information.

The Littelfuse AA1-B2-12-615-2D1-C is a single-pole magnetic circuit breaker with hydraulic delay, designed for overcurrent protection in electrical systems. It is rated for 15 amps of continuous current at a maximum voltage of 277 volts AC.

 

This circuit breaker uses a magnetic (hydraulic delay) trip mechanism, which provides reliable overcurrent protection with a time delay characteristic that is inversely proportional to the fault current. The lever actuator allows for manual on/off control and reset. The unit is designed for panel mount installation.

 

The AA1-B2-12-615-2D1-C carries approvals from CCC, CSA, and UL, indicating compliance with major international safety standards. It is listed as RoHS3 compliant and REACH unaffected.
