CMB-203-11CNN-W-A Description

Short technical summary and product information.

The Littelfuse CMB-203-11CNN-W-A is a single-pole thermal circuit breaker designed for overcurrent protection in electrical circuits. It is rated for 20A continuous current at 250V AC, making it suitable for a variety of power distribution and equipment protection applications.

 

The breaker features a push-to-reset actuator mechanism, allowing manual reset after a fault condition. It is designed for panel mount installation, providing a secure and accessible mounting solution for control panels and enclosures.

 

As a thermal-type breaker, it responds to heat generated by overcurrent conditions, offering reliable and cost-effective circuit protection. The non-illuminated design simplifies the interface for applications where visual indication is not required.
