Ohleats 4 Pin Starter Relay 12V 30A Automotive

Description

Product Overview

The Ohleats 4 Pin Starter Relay is engineered for demanding automotive environments where reliable high‑current switching is essential. Constructed with a black plastic shell that provides excellent insulation, waterproofing and flame retardancy, the relay houses copper pins and a silver‑alloy contact design that resists oxidation and maintains low contact resistance. The electromagnetic coil is made from all‑copper wire with an 80 Ω resistance, operating at 24 V DC to deliver a consistent 30 A current rating. Available in 2‑piece and 4‑piece packs, the relay comes in both 4‑pin (12 V/24 V) and 5‑pin (12 V) configurations, giving installers the flexibility to match a wide range of vehicle wiring harnesses. Each unit meets CCC specifications and is backed by Ohleats’ reputation for quality automotive components.

Usage

Designed for straightforward through‑hole mounting on vehicle PCBs or chassis brackets, this relay is ideal for controlling high‑current loads such as electric cooling fans, water pumps, fuel pumps, taillight circuits and power‑door lock solenoids. Its manual operation mode allows direct wire‑to‑relay connections without the need for additional tools, making it a favorite among DIY enthusiasts and professional mechanics alike. Whether you are upgrading an older vehicle’s electrical system or repairing a modern car’s power relay, the Ohleats starter relay offers a dependable solution that fits within standard automotive fuse boxes and relay sockets.
