BB2-B0-42-630-561-D Description

Short technical summary and product information.

This circuit breaker from Littelfuse is designed for overcurrent protection in a wide range of applications. It features a magnetic hydraulic delay mechanism that provides precise and reliable tripping characteristics. With a current rating of 30A and voltage rating of 250V, it is suitable for many industrial and commercial circuits. The 2-pole configuration allows for simultaneous disconnection of both lines. The panel mount design with a lever actuator facilitates easy installation and manual reset. This breaker has no illumination, making it suitable for ambient applications where indicator lights are not required. Commonly used in power distribution panels, motor control centers, and equipment protection. The hydraulic delay feature provides time-delayed trip to avoid nuisance tripping from inrush currents.
