The Littelfuse MM1-B-32-440-1-1BB-B-C is a single-pole magnetic circuit breaker with hydraulic delay, designed for overcurrent protection in a variety of applications. It is rated for 4A continuous current at 250V AC/DC, providing reliable circuit interruption under fault conditions.
The breaker uses a magnetic (hydraulic delay) trip mechanism, which offers predictable time-current characteristics and is less sensitive to ambient temperature changes compared to thermal breakers. The lever actuator allows for manual reset and on/off control.
This component is designed for panel mount installation, making it suitable for use in control panels, power distribution units, and industrial equipment where a robust, resettable overcurrent protection device is required. It holds approvals from CCC, CSA, and UL1077, indicating compliance with international safety standards.
