AB3-B0-24-625-5D1-C Description

Short technical summary and product information.

This Littelfuse AB3 series circuit breaker is a 3-pole, magnetic hydraulic delay type rated for 25A continuous current at 277V. It features a panel mount design with a lever actuator and is not illuminated. The breaker is approved by UL, CSA, and CCC, making it suitable for a variety of industrial and commercial applications.

 

Magnetic hydraulic delay technology provides reliable overcurrent protection by combining a magnetic coil for short-circuit response with a hydraulic delay element for time-delay characteristics. This offers precise coordination and reduces nuisance tripping.

 

The panel mount configuration allows for easy installation in distribution panels and control enclosures. The lever actuator provides clear visual indication of the breaker state and manual operation.
