MB2-B-22-618-1-A26-2-C Description

Short technical summary and product information.

The Littelfuse MB2-B-22-618-1-A26-2-C is a 2-pole magnetic hydraulic delay circuit breaker designed for overcurrent protection in a variety of applications. It is rated for 18A continuous current at 250V, providing reliable interruption under fault conditions. The hydraulic delay mechanism offers time-delay characteristics that help avoid nuisance tripping from transient currents.

 

This circuit breaker uses a rocker actuator for manual on/off control and reset. It is configured for panel mount installation, making it suitable for integration into control panels, power distribution units, and industrial equipment. The 2-pole design allows simultaneous protection of two lines in single-phase or split-phase systems.

 

With no illumination, the actuator provides a clean, non-lighted interface. The magnetic hydraulic trip technology ensures consistent performance across a range of ambient conditions, though operating temperature specifications are not provided in the available data.
