MT1-B-24-630-1-A21-B-C Description

Short technical summary and product information.

The Littelfuse MT1-B-24-630-1-A21-B-C is a single-pole magnetic circuit breaker with hydraulic delay. It is rated for 30A at 250V and features a push-pull actuator. This breaker is designed for panel mount installation and is not illuminated.

 

This circuit breaker uses a magnetic (hydraulic delay) mechanism for overcurrent protection. The hydraulic delay provides time-delayed tripping that handles inrush currents while still protecting against sustained overloads and short circuits.

 

The panel mount design allows for straightforward installation in control panels, equipment enclosures, or power distribution systems.
