ME1-B-34-420-1-A12-B-C Description

Short technical summary and product information.

The Littelfuse ME1-B-34-420-1-A12-B-C is a single-pole magnetic circuit breaker with a hydraulic delay mechanism. It is rated for 2 amps at 250 volts AC/DC and uses a rocker actuator for manual reset. The breaker is designed for panel mount installation and is suitable for overcurrent protection in a variety of industrial and commercial applications.

 

This circuit breaker employs a magnetic trip element with a hydraulic delay, providing time-delayed overcurrent protection that can withstand brief inrush currents without nuisance tripping. The 1-pole configuration makes it ideal for protecting individual load circuits. The rocker actuator offers a clear visual indication of the breaker state.

 

The ME1-B-34-420-1-A12-B-C carries approvals from CCC, CSA, and UL1077, indicating compliance with international safety standards for supplementary protectors. It is RoHS3 compliant, REACH unaffected, and has an MSL of 1 (unlimited).
