CLB-253-11BNN-B-A/25 Description

Short technical summary and product information.

The Littelfuse CLB-253-11BNN-B-A/25 is a single-pole thermal circuit breaker designed for overcurrent protection in a variety of applications. It is rated for 25A continuous current at 250V AC/DC, providing reliable protection against sustained overloads.

 

This breaker uses a thermal mechanism that responds to heat generated by excessive current, offering a time-delay characteristic that helps avoid nuisance tripping from temporary inrush currents. The push-to-reset actuator allows for easy manual reset after a trip event.

 

The device is panel mounted, making it suitable for integration into control panels, power distribution units, and equipment enclosures. It carries approvals from CE, cUL, TUV, UL1077, and UL1500, indicating compliance with international safety standards.
