MT1-B-12-420-1-B23-B-T

The MT1-B-12-420-1-B23-B-T is a single-pole circuit breaker manufactured by Littelfuse Inc. Designed for electrical overcurrent protection, this component provides reliable circuit interruption in industrial and commercial applications. It is rated for a continuous current of 2A and operates at a maximum voltage of 250V.

This breaker utilizes a magnetic hydraulic delay mechanism to handle temporary inrush currents without nuisance tripping, ensuring stable operation during equipment startup. The unit employs a push-pull actuator type for manual reset functionality after a trip event. Illumination is not included in this configuration.

For installation, the device supports panel mounting, allowing secure integration into control panels and enclosures. Its robust construction makes it suitable for protecting sensitive electronics and power distribution systems where precise overcurrent management is required. Engineers should verify enclosure cutout dimensions and terminal compatibility during system design.
