CLB-043-11ANN-W-A Description

Short technical summary and product information.

The CLB-043-11ANN-W-A is a thermal circuit breaker from Littelfuse Inc. It is rated for 4A continuous current at 250V AC/DC, with a single-pole configuration. The breaker uses a thermal mechanism to provide overcurrent protection, automatically tripping when current exceeds the rated value.

 

This circuit breaker features a push-to-reset actuator, allowing manual reset after a trip event. It is designed for panel mount installation, making it suitable for use in control panels, power distribution units, and other equipment requiring reliable circuit protection. The breaker is approved by CE, cUL, TUV, UL1077, and UL1500, ensuring compliance with international safety standards.

 

The compact design and robust construction make it ideal for applications where space is limited. The thermal trip characteristic provides time-delayed response, preventing nuisance tripping from transient currents. This component is commonly used in industrial machinery, automotive systems, and power supplies.
