MT1-M-12-620-1-A12-B-M Description

Short technical summary and product information.

The MT1-M-12-620-1-A12-B-M is a 1-pole magnetic hydraulic delay circuit breaker manufactured by Littelfuse Inc. It is rated for 20A at 250V and uses a magnetic (hydraulic delay) trip mechanism, providing reliable overcurrent protection. The breaker is designed for panel mount installation and features a push-pull actuator for manual reset. It has no illumination. The unit is approved by CCC, CSA, and UL1077.

 

This circuit breaker is suitable for use in a variety of industrial and commercial applications where dependable circuit protection is required. The magnetic hydraulic delay offers time-delayed trip characteristics, allowing for temporary inrush currents without nuisance tripping. The panel mount design simplifies integration into control panels or equipment enclosures. The push-pull actuator provides easy manual operation.

 

The product is RoHS3 compliant, REACH unaffected, and has MSL 1 moisture sensitivity level. The part number cross-references to distributor part 432-MT1-M-12-620-1-A12-B-M-ND.
