The Littelfuse MD1-B-64-620-1-A36-B-E is a single-pole magnetic circuit breaker with hydraulic delay. It is rated for 20A at 250V and features a rocker actuator. The breaker uses a magnetic (hydraulic delay) mechanism for reliable overcurrent protection. This design provides a time-delay characteristic that allows for temporary inrush currents without nuisance tripping.
The unit is panel mounted and has no illumination. It is approved by CCC, CSA, TUV, and UL agencies, ensuring compliance with international safety standards. The breaker is RoHS3 compliant and REACH unaffected, with an MSL of 1 (unlimited).
Typical applications include power distribution, industrial control panels, and equipment protection where a robust, time-delay magnetic circuit breaker is required. The compact panel-mount design simplifies installation in enclosures.
