Relays With Resistor

Upgrade your vehicle’s electrical system with our specialist range of relays with resistor at Mid Ulster Rotating Electrics. These relays incorporate a built-in resistor to help suppress voltage spikes when the coil de-energises, protecting wiring and electroniccomponents. 

Available in both 12 V and 24 V versions, these relays are ideal for automotive, agricultural, trailer and industrial use. Particularly in lighting circuits, fan systems, pumps or other high-current loads where protection and reliability matter.

At our Cookstown-based shop in Northern Ireland, we stock trusted brands, offer expert advice and provide fast UK dispatch. Find the right relay with resistor for your application and install with confidence.
