MM1-B-94-480-1-1FB-B-C Description

Short technical summary and product information.

The Littelfuse MM1-B-94-480-1-1FB-B-C is a single-pole magnetic circuit breaker with hydraulic delay, designed for overcurrent protection in electrical circuits. It is rated for 8 amps at 250 volts AC/DC. The breaker uses a magnetic trip mechanism with hydraulic delay to provide time-delayed tripping for transient surges while ensuring fast response to sustained overcurrents. The actuator type is a lever, allowing manual reset. This circuit breaker is panel mounted and has no illumination. It is approved by CCC, CSA, and UL1077, making it suitable for industrial and commercial applications. The compact design fits standard panel cutouts. The product is RoHS compliant and has an MSL of 1 (unlimited). Note: The datasheet is not available in this listing; refer to manufacturer for detailed specifications.
