CMB-153-27KNN-R-M Description

Short technical summary and product information.

The Littelfuse CMB-153-27KNN-R-M is a thermal circuit breaker designed for overcurrent protection in low-voltage applications. It is rated for 15 amps continuous current at 250 volts AC/DC and features a single-pole configuration.

 

The breaker uses a thermal mechanism to trip when current exceeds the rated value for a sustained period, providing reliable protection against overloads. The push-to-reset actuator allows manual reset after a trip event.

 

This component is approved by multiple agencies including CE, cUL, TUV, UL1077, and UL1500, ensuring compliance with international safety standards. It is designed for panel mount installation, making it suitable for use in control panels, power distribution units, and industrial equipment.
