CA1-B0-12-620-321-C Description

Short technical summary and product information.

The Littelfuse CA1-B0-12-620-321-C is a single-pole magnetic circuit breaker with hydraulic delay, rated for 20A at 480V. This circuit breaker uses a lever actuator for manual operation and is designed for panel mounting.

 

The magnetic hydraulic delay mechanism provides reliable overcurrent protection for a variety of applications. The 1-pole configuration makes it suitable for single-phase circuits requiring branch circuit protection.

 

This circuit breaker is intended for use in electrical distribution and equipment protection applications where panel mounting is required. The lever actuator provides clear visual indication of the breaker state and allows for easy manual reset.

 

As a magnetic-type breaker, it offers fast response to short-circuit conditions while the hydraulic delay helps prevent nuisance tripping during temporary inrush currents.
