MN1-B-20-445-2-2DB-B-C Description

Short technical summary and product information.

The Littelfuse MN1-B-20-445-2-2DB-B-C is a single-pole magnetic circuit breaker with hydraulic delay, designed for overcurrent protection in electrical circuits. It is rated for 4.5A continuous current at 250V AC/DC. The magnetic hydraulic delay mechanism provides time-delayed tripping, making it suitable for applications with high inrush currents such as motor starting or transformer energization. The breaker uses a lever actuator for manual reset and is mounted directly to a panel. It carries approvals from CCC, CSA, and UL1077, ensuring compliance with international safety standards. This component is commonly used in industrial control panels, power distribution systems, and equipment requiring reliable circuit protection.
