CMB-103-11C3A-W-A Description

Short technical summary and product information.

The Littelfuse CMB-103-11C3A-W-A is a single-pole thermal circuit breaker designed for overcurrent protection in a variety of applications. It is rated for 10A continuous current at 250V AC/DC, providing reliable protection against sustained overloads.

 

The breaker uses a thermal mechanism that responds to heat generated by excessive current, tripping the circuit to prevent damage to downstream components. It features a push-to-reset actuator, allowing manual reset after a trip event. The device is designed for panel mount installation, making it suitable for integration into control panels, power distribution units, and equipment enclosures.

 

The CMB-103-11C3A-W-A carries approvals from CE, cUL, TUV, UL1077, and UL1500, indicating compliance with international safety standards for supplementary circuit protection.
