The Littelfuse MU2-B-24-615-1-B21-B-C is a 2-pole magnetic hydraulic delay circuit breaker from the MU2 series. It is rated for 15A continuous current at 250V AC/DC and features a push-to-reset actuator for manual reset after a fault. The breaker uses a panel mount design suitable for front-panel installation in control enclosures and equipment.\n\nThis circuit breaker carries approvals from CCC, CSA, and UL1077, making it compliant for industrial and commercial applications requiring recognized safety standards. The magnetic hydraulic delay mechanism provides time-delayed overcurrent protection, allowing harmless inrush currents without nuisance tripping.\n\nThe 2-pole configuration enables simultaneous disconnection of both lines in a circuit, enhancing safety for dual-supply or split-phase systems. Typical applications include power distribution, motor control, HVAC equipment, and industrial machinery where reliable circuit protection is critical.
