12V Normally Open Automotive Relay, 200A Reference

Switch a suitable high-current circuit through a separate control connection. This 12 V normally open relay suits installers comparing contact, duty and wiring requirements for a vehicle electrical design.

• ✅ Separate control from the load — The relay coil operates the main contact arrangement.
• ✅ Keep the circuit open at rest — Normally open contacts close only when the relay is correctly energised.
• ✅ Mount the component in a planned position — A moulded bracket provides a fixing point.
• ✅ Connect through stud terminals — Two main studs provide the load connections.

Check Duty and Terminal Identification Before Wiring

The relay is described with a 200 A reference, copper terminals, two small pins and two main studs. Verify the actual component's coil and contact markings before connecting.

Do not rely on the conflicting polarity instructions in the original text. A split-charge application requires a properly designed control and protection arrangement; the relay is not an automatic battery-management system by itself.
