AK1-B0-12-620-1C1-D Description

Short technical summary and product information.

The Littelfuse AK1-B0-12-620-1C1-D is a single-pole magnetic hydraulic delay circuit breaker from the AK1 series. It is rated for 20A continuous current at 277V AC, providing reliable overcurrent protection for a variety of applications.

 

The breaker uses a magnetic hydraulic delay mechanism, which offers precise trip characteristics and is less sensitive to ambient temperature changes than thermal breakers. The rocker actuator provides a clear on/off indication and easy manual reset.

 

This component is designed for panel mount installation, making it suitable for use in control panels, power distribution units, and industrial equipment where a robust, resettable circuit protection solution is required.
