Key benefits — why you need this relay Reliable engine starting: copper terminal and robust contacts provide consistent electrical engagement for engine start systems, reducing failed starts and unreliable operation. current capacity: 100 A contact rating handles heavyduty loads for automotive, marine, agricultural and industrial equipment. Stable control and long service life: coil power options (4.8W / 2.4W) and a design that resists overheating deliver steady connectivity and longlasting reliability. Versatile replacement: fits starter, preheat and powerswitch roles across vehicles and equipment, simplifying repairs and parts stocking. What it does (functions and performance) Starter relay function: engages the starter motor reliably for cars, trucks and machinery. Preheat and power switching: works as a preheat relay or general power switch in engine control systems and equipment. performance switching: normally open 2pin contact configuration, rated for 12 VDC switching with a robust 100 A current capability for heavy loads. Control coil options: 4.8W and 2.4W coil power choices provide stable output and efficient operation for longterm use. Thermal resilience: designed to resist overheating under demanding conditions for dependable performance. Key attributes (material, compatibility, and form) Terminal material: conductivity copper terminal for lowresistance connections and reliable current transfer. Contact rating: 100 A at 12 VDC (normally open). Pins: 2pin configuration for straightforward replacement and wiring. Compatibility: intended as a replacement relay for cars, trucks, harvesters, cranes, generators, marine craft, and industrial control circuits; also suitable for smart home and industrial switching applications where a 12 V relay is required. Durability: built for demanding conditions and continuous operation. Practical applications — example use scenarios Vehicle starter replacement: swap into cars or trucks to restore reliable engine cranking after the original starter relay fails. Agricultural and construction equipment: use as a starter or preheat relay in harvesters, cranes and other machinery that require current switching in rugged environments. Marine and generator power control: handle load 12 VDC switching tasks on boats or portable generators where a 100 A rating is required. Industrial and smarthome control: use the 4.8W/2.4W coil option for lowvoltage control circuits that need stable, longterm switching performance. Why it stands out Combines a conductivity copper terminal with a heavyduty 100 A switching capability and efficient coil power options for a balance of control stability and currenthandling strength. Designed specifically to withstand demanding operating conditions while remaining a direct, widely compatible replacement for engine control and powerswitching needs. Replacement note Supplied as a replacement starter/preheat/powerswitch relay with a normally open 2pin configuration, rated for 12 VDC switching and 100 A continuous current; coil power options are 4.8W and 2.4W. A replacement part that delivers longlasting reliability.
