MT2-B-64-440-1-A21-B-E Description

Short technical summary and product information.

The Littelfuse MT2-B-64-440-1-A21-B-E is a 2-pole magnetic circuit breaker with hydraulic delay, designed for panel mounting. It is rated for 4A at 250V and features a push-pull actuator. This circuit breaker is not illuminated. It holds approvals from CCC, CSA, TUV, and UL, ensuring compliance with international standards. Magnetic circuit breakers with hydraulic delay provide reliable overcurrent protection with a time-delay characteristic that minimizes nuisance trips in applications with transient currents. The push-pull actuation allows for manual reset and on/off control. The panel mount design is suitable for integration into control panels, power distribution units, and industrial equipment enclosures.
