The Littelfuse MM1-B-24-630-1-1DA-B-C is a single-pole magnetic circuit breaker featuring a hydraulic delay mechanism. It is rated for 30A of continuous current at 250V AC/DC, providing reliable overcurrent protection for a variety of electrical systems. The magnetic (hydraulic delay) design offers precise trip characteristics that are less sensitive to ambient temperature changes compared to thermal breakers.
This circuit breaker uses a lever actuator for manual on/off control and is designed for panel mount installation. It carries approvals from CCC, CSA, and UL1077, indicating compliance with international safety standards for supplementary circuit protection. The non-illuminated actuator keeps the design simple and robust for industrial and commercial environments.
Typical applications include power distribution, control panels, and equipment branch circuit protection where a 1-pole, 30A rated breaker is required. The hydraulic delay feature allows for brief inrush currents without nuisance tripping, making it suitable for loads with moderate starting surges.
