CLB-253-12CNN-W-A Description

Short technical summary and product information.

The Littelfuse CLB-253-12CNN-W-A is a single-pole thermal circuit breaker designed for overcurrent protection in a variety of electrical systems. It is rated for a continuous current of 25A at a voltage of 250V. The breaker uses a thermal mechanism to trip when an overload condition is detected, providing reliable protection for connected circuits.

 

The actuator type is push to reset, which allows for manual reset after a trip event. This circuit breaker is intended for panel mount installation, making it suitable for use in control panels, power distribution units, and other equipment where a robust, resettable overcurrent protection device is required.

 

The CLB-253-12CNN-W-A carries approvals from CE, cUL, TUV, UL1077, and UL1500, indicating compliance with international safety standards for circuit protection devices.
