CLB-103-12C5N-B-A/10 Description

Short technical summary and product information.

The Littelfuse CLB-103-12C5N-B-A/10 is a single-pole thermal circuit breaker from the CLB-103 series. It is rated for 10A continuous current at 250V AC/DC, providing reliable overcurrent protection for a variety of electrical circuits.

 

The breaker uses a thermal trip mechanism that responds to sustained overcurrent conditions, making it suitable for applications where nuisance tripping from brief inrush currents must be minimized. The push-to-reset actuator allows for manual reset after a trip event, providing clear user feedback.

 

This component is designed for panel mount installation, offering a compact and robust solution for protecting wiring and downstream equipment. The non-illuminated actuator simplifies the design and reduces power consumption.
