MCS Circuit Breakers

15 products — part of all Circuit Breakers

MCS circuit breakers give Harley-Davidson owners the resettable overcurrent protection devices that guard specific circuits within the motorcycle's electrical system. Unlike a blown fuse that leaves a rider stranded until a replacement is found, a circuit breaker trips under fault conditions and can be reset once the fault is cleared, making them a practical upgrade for touring riders and those running additional electrical accessories. MCS supply direct-fit circuit breakers designed to integrate into Harley-Davidson wiring looms without modification, covering the amperage ratings used across the main model families from Sportster to Touring. Correct amperage selection is critical — a breaker rated too high will not protect the wiring harness under genuine overcurrent conditions. Iron City Motorcycles, an authorised Harley-Davidson dealer in Leeds, stocks MCS circuit breakers alongside a full electrical components and accessories range for Harley-Davidson models.
