- Never go beyond its capabilities. Try to stay 10 to 15% below what the rate is for
- 12-volt 5-prong relay. Excellent water-repellent and dustproof ability, but not using it in water
- Be careful when inserting the relay into the socket. If you force it, you will bend the female connectors
- Primary leads use 12 a.w.g tinned copper wire. Coil leads use 16 a.w.g
- Nominal Coil Voltage: 12 V DC; Coil Power: 1.8 W; Coil Resistance: 80 Ω; Must Operate Voltage: 6~8 V DC; Must Release Voltage: 0.6~3.6 V DC; Maximum Applied Voltage: 15.6 V DC
- Integrated Diode: Each relay includes a built-in diode that suppresses induced voltage during switching, safeguarding your electrical components from potential damage.
- Small size/Low power consumption/High contact voltage/ High sensitivity.
- Contact Material: Ag Alloy / Contact Resistance: ≤ 100MΩ.
- Minimum operating voltage 8V, corresponding minimum operating current is 100mA; Standard operating voltage 12V, corresponding standard operating current is 150mA.
- Life Expectancy Electrical: 100,000 Operation, Life Expectancy Mechanical: 10,000,000 Operation.
- High switching capability: Normally open 40A/14V DC and normally close 30A/14V DC. Suitable for Nilight LED light bar wiring harness kit
- Premium quality: Durable relay and harness socket with 5 wires; Made by high-grade materials to ensure superior quality and long lifespan

- Package include: 5 x relay and 5 x relay socket with wires.Fit type: Universal fit
- Upgraded Version - Automotive relays built in fuse socket included 30A blade fuse with heavy duty 14AWG wires for main contact. no need of a separate fuse holder, saving space and money. 4-Pin SPST (Single Pole Single Throw) Relay.
- Mounting Design Feature - The interlocking mounting design of unique male and female slot on each socket edge, connect relays together and manage cables easily, offering clean and neat installation.
- Easy Wiring - The relay sockets come with color-labeled wires for load/accessories convenient wiring. Black - Ground (85), Red - VDC (30), White - Trigger (86), Blue - Output N/O (87)
- Wide Application - Widely used in car keys power control, over-load protection, trunk release, polarity change, power door lock/actuator control, change a low current output to high current, add ignition/accessory outputs, control motors/other electronics etc.
- Set includes 5 relays, 5 relay harnesses, and 5 30A blade fuses.
