MT1-B-34-620-1-A21-B-E Description

Short technical summary and product information.

The MT1-B-34-620-1-A21-B-E is a single-pole magnetic (hydraulic delay) circuit breaker from Littelfuse. It is rated for 20A continuous current at 250V, providing reliable overcurrent protection for electrical systems.

 

This circuit breaker utilizes a magnetic hydraulic delay mechanism, which combines the fast response of magnetic trip with a time-delay characteristic to handle temporary surge currents without nuisance tripping. The push-pull actuator allows for manual reset and on/off control.

 

Designed for panel mount installation, the MT1-B series offers robust construction suitable for industrial and commercial applications. It is approved by CCC, CSA, TUV, and UL agencies, ensuring compliance with international safety standards.

 

The circuit breaker has no illumination and is available in a compact 1-pole configuration, making it ideal for space-constrained control panels and power distribution systems.
