The CMB-033-27JNN-W-A/03 is a single-pole thermal circuit breaker manufactured by Littelfuse Inc. It is rated for 3A of continuous current at 250V AC/DC, providing reliable overcurrent protection for a variety of applications. The thermal breaker mechanism ensures a time-delayed trip response to sustained overloads, resetting automatically after cooling or manually via the push-to-reset actuator.
This circuit breaker features a panel mount design for secure installation in control panels, power distribution units, and equipment enclosures. The push-to-reset actuator allows for easy manual reset after a trip event. The part is non-illuminated and carries approvals from CE, cUL, TUV, UL1077, and UL1500, indicating compliance with international safety standards for supplementary protectors and marine applications.
