The AA1-B2-34-630-1B1-C is a single-pole magnetic circuit breaker from Littelfuse, designed for overcurrent protection in electrical systems. It has a current rating of 30A and a voltage rating of 277V, making it suitable for lighting and general power distribution applications. The breaker utilizes a magnetic (hydraulic delay) trip mechanism, which provides time-delayed tripping for handling inrush currents without nuisance tripping.
The breaker is panel mounted with a lever actuator for manual operation. It is not illuminated. The device carries approvals from CCC, CSA, and UL, indicating compliance with international safety standards. The product is RoHS3 compliant, REACH unaffected, and has an MSL of 1 (unlimited).
This circuit breaker is ideal for use in industrial control panels, HVAC equipment, and other applications requiring reliable overcurrent protection with a compact 1-pole form factor. The hydraulic delay characteristic allows it to handle temporary overloads while still providing protection against sustained faults.
