MN1-B-20-620-1-1CB-B-B Description

Short technical summary and product information.

The Littelfuse MN1-B-20-620-1-1CB-B-B is a single-pole magnetic circuit breaker featuring hydraulic delay for overcurrent protection. It is rated for 20A continuous current at 250V AC/DC. The breaker uses a magnetic (hydraulic delay) mechanism, which provides reliable protection against short circuits and overloads. The lever actuator allows manual reset and on/off control. This circuit breaker is designed for panel mount installation, making it suitable for industrial control panels, power distribution units, and equipment requiring robust circuit protection. The non-illuminated actuator simplifies operation. The part is compliant with RoHS3 and REACH unaffected, though these compliance statuses are unverified.
