MT1-U-30-020-1-C21-B-C Description

Short technical summary and product information.

The Littelfuse MT1-U-30-020-1-C21-B-C is a single-pole magnetic circuit breaker with a hydraulic delay mechanism. It is rated for 20mA of current and 250V of voltage, making it suitable for overcurrent protection in low-power circuits.

 

The breaker uses a magnetic (hydraulic delay) trip mechanism, which provides a time-delayed response to overcurrent conditions. This design helps prevent nuisance tripping from temporary inrush currents while still providing reliable protection against sustained overloads and short circuits.

 

The actuator type is push-pull, allowing for manual reset and circuit interruption. The device is designed for panel mount installation. It carries approvals from CCC, CSA, and UL1077, indicating compliance with relevant safety standards.
