The Littelfuse MM1-B-20-430-1-1BB-B-E is a single-pole magnetic circuit breaker utilizing a hydraulic delay mechanism for overcurrent protection. It is rated for a continuous current of 3A and a voltage of 250V, making it suitable for a variety of electrical systems requiring reliable circuit interruption.
This circuit breaker features a lever actuator for manual reset and is designed for panel mount installation. The magnetic (hydraulic delay) breaker type provides a time-delay characteristic that allows for temporary inrush currents without nuisance tripping, while still offering fast response to sustained overloads and short circuits.
The MM1-B series is built for durability and compliance, holding approvals from CCC, CSA, TUV, and UL agencies. It is a non-illuminated unit, suitable for applications where visual indication of the breaker state is not required.
