The Littelfuse MU1-B-24-250-1-A21-B-C is a magnetic hydraulic delay circuit breaker designed for overcurrent protection in electrical circuits. It is rated for 500mA continuous current and 250V AC/DC, making it suitable for a variety of industrial and commercial applications.
This single-pole breaker uses a magnetic (hydraulic delay) trip mechanism that provides precise time-delay characteristics, allowing it to withstand short inrush currents without nuisance tripping. The push-to-reset actuator offers manual reset after a fault condition, and the panel mount design allows for easy installation in control panels or enclosures.
The breaker is non-illuminated and has no additional auxiliary contacts. It is approved by CCC, CSA, and UL1077, ensuring compliance with major safety standards. The RoHS and REACH statuses are noted but unverified, so buyers should confirm compliance with their specific requirements.
