The Littelfuse MU1-B-62-230-1-C21-B-D is a single-pole magnetic circuit breaker with hydraulic delay, designed for overcurrent protection in a variety of electrical systems. It is rated for a continuous current of 300mA at a maximum voltage of 250V, making it suitable for low-power branch circuit protection.
This circuit breaker uses a magnetic (hydraulic delay) trip mechanism, which provides a time-delayed response to overcurrent conditions. The hydraulic delay allows the breaker to tolerate temporary inrush currents without nuisance tripping, while still providing reliable protection against sustained overloads and short circuits.
The device is panel mounted and features a push-to-reset actuator, allowing for manual reset after a trip event. It is not illuminated. The breaker is approved by CCC, CSA, UL, and VDE, indicating compliance with major international safety standards.
