AA1-B2-52-610-1D1-C Description

Short technical summary and product information.

The AA1-B2-52-610-1D1-C is a single-pole magnetic circuit breaker manufactured by Littelfuse Inc. It is rated for 10A continuous current at 277V AC/DC and uses a hydraulic-magnetic delay mechanism, providing reliable overcurrent protection without thermal dependency. The breaker has a compact panel mount design with a lever actuator.

 

This circuit breaker is approved by CCC, CSA, and UL, ensuring compliance with international safety standards. It comes in a non-illuminated configuration and is suitable for a variety of industrial and commercial applications where precise trip characteristics are required. The hydraulic delay allows for high inrush immunity while maintaining accurate overload protection.

 

With a panel mount style, the breaker is easy to install in control panels and enclosures. The lever actuator provides clear visual indication of the circuit state. Its 1-pole design makes it ideal for single-phase circuits or individual branch protection.
