MA2-B-12-620-1-A36-B-E Description

Short technical summary and product information.

The Littelfuse MA2-B-12-620-1-A36-B-E is a 2-pole magnetic circuit breaker with hydraulic delay, designed for overcurrent protection in electrical circuits. It is rated for 20A continuous current at 250V, providing reliable interruption under fault conditions.

 

The magnetic hydraulic delay mechanism offers time-delayed tripping, making it suitable for applications with inrush currents while maintaining fast response to high overcurrents. The breaker uses a rocker actuator for manual on/off control and is not illuminated.

 

This circuit breaker is panel mountable, allowing installation directly into equipment panels. It holds approvals from CCC, CSA, TUV, and UL, indicating compliance with major international safety standards.

 

Suitable for use in industrial control panels, power distribution, and other applications requiring dependable circuit protection.
