MF1-B-34-610-3-JA5-B-C Description

Short technical summary and product information.

The Littelfuse MF1-B-34-610-3-JA5-B-C is a single-pole magnetic hydraulic delay circuit breaker designed for overcurrent protection in a variety of applications. It is rated for 10A continuous current at 250V AC/DC, providing reliable interruption under fault conditions.

The breaker uses a magnetic (hydraulic delay) trip mechanism, offering predictable time-delay characteristics that help avoid nuisance tripping from transient inrush currents. The actuator is a rocker type with green illumination, operating at 9 to 16V nominal. It is designed for panel mounting, making it suitable for front-panel installation in control cabinets, power distribution units, and industrial equipment.

This component carries approvals from CCC, CSA, and UL1077, indicating compliance with North American and Chinese safety standards. The product is RoHS3 compliant and has an MSL of 1 (unlimited).
