The Littelfuse MA1-B-64-620-1-A24-B-C is a single-pole hydraulic magnetic circuit breaker designed for overcurrent protection. It is rated for 20A continuous current and 250V AC/DC, making it suitable for a variety of industrial and commercial applications. The hydraulic magnetic mechanism provides a time-delayed trip characteristic, allowing for inrush currents without nuisance tripping.
This circuit breaker utilizes a rocker actuator for manual on/off control and is designed for panel mount installation. With one pole, it is ideal for protecting individual branch circuits. The compact design integrates easily into control panels, distribution boards, and equipment enclosures.
The breaker carries approvals from CCC, CSA, and UL1077, indicating compliance with international safety standards. The panel mount configuration simplifies integration into existing equipment. Environmental compliance data for RoHS, REACH, and MSL is unverified and should be confirmed with the manufacturer.
