MT1-B-14-620-3-A22-B-E Description

Short technical summary and product information.

The Littelfuse MT1-B-14-620-3-A22-B-E is a single-pole magnetic circuit breaker featuring a hydraulic delay mechanism. It is rated for 20A of continuous current at 250V, making it suitable for overcurrent protection in a variety of electrical systems.

 

The breaker uses a magnetic (hydraulic delay) trip action, which provides a time-delayed response to overcurrent conditions, allowing for brief inrush currents without nuisance tripping. The push-pull actuator offers a manual on/off control interface.

 

This component is designed for panel mount installation, providing a secure and reliable mounting solution for control panels and equipment enclosures. The MT1-B series is known for its robust construction and consistent performance in demanding environments.
