AA1-B0-12-630-1T2-C Description

Short technical summary and product information.

The Littelfuse AA1-B0-12-630-1T2-C is a single-pole magnetic circuit breaker featuring a hydraulic delay mechanism. It is rated for a continuous current of 30A at 277V AC. The breaker uses a magnetic (hydraulic delay) trip characteristic, providing reliable overcurrent protection with a time delay that is inversely proportional to the overload current.

 

This circuit breaker is designed for panel mount installation and is operated via a lever actuator. It is not illuminated. The part is approved by CCC, CSA, and UL, indicating compliance with major international safety standards.

 

Typical applications include power distribution, industrial control panels, and equipment requiring branch circuit protection. The hydraulic-magnetic design offers stable performance over a wide temperature range, making it suitable for environments where ambient temperature varies.
