Collection: Relays, Contactors & Fuses

Relays, contactors and fuses switch or protect electrical circuits in vehicles, engines, machinery, chargers and industrial control systems. Components with the same case size can have different coil voltages, current ratings, contact logic, pin layouts and time-current characteristics.

• Match the printed part number and circuit function.
• Verify coil or system voltage, current rating and contact configuration.
• Compare pin layout, mounting, dimensions and fuse type or breaking capacity.

Read each listing carefully to confirm whether the item is a single component, an assembly or a kit, and whether seals, connectors, fittings or mounting hardware are included. Installation, adjustment and system checks should always follow the equipment manufacturer's service procedure.

Fitment FAQ: Can a relay with the same pin count be substituted? Only when the pin functions, coil rating, contact form and load capacity are equivalent.

If any reference or measurement is uncertain, compare the removed component and ask Stellar Spares before ordering. Eligible returns are governed by the published 90-day return policy.
