## Description

The Littelfuse CLB-403-11A1B-B-A is a thermal circuit breaker designed for overcurrent protection. It is rated for 40A continuous current at 250V and features a single-pole construction with a push-to-reset actuator. The breaker is non-illuminated and mounts directly to a panel, making it suitable for a variety of industrial and commercial applications.

The thermal breaker mechanism provides reliable protection against sustained overloads by using a bimetallic strip that trips when current exceeds the rated value for a period of time. The push-to-reset actuator allows manual reset after a trip event, indicating that the circuit has been interrupted.

This component is certified by multiple agencies including CE, cUL, TUV, UL1077, and UL1500, which ensures compliance with international safety standards. It is commonly used in power distribution, control panels, and marine applications where robust overcurrent protection is required.
