상품 특징

• Specs & key features: electromagnetic relay with 12VDC coil, 40A rated switching current (at 12VDC), 4-pin contact arrangement 1A / SPST-NO; coil power 1.6W; coil resistance about 90Ω (±10%); insulation resistance 100MΩ (500VDC); electrical life 100,000 cycles / mechanical life 1,000,000 cycles; operate/release time ≤10ms; ambient temp -40°C to +125°C; vibration 10–40Hz (1.5mm) & shock 147m/s² (11ms); 6.3x0.8mm blade terminals; AgSnO2 contacts; nylon PA66 base/cap. OE#: ZTV4/012-1H (JD1912-type 4-pin 40A relay) for high-current circuit switching in 12V systems.
• Install/replace tips: disconnect the battery first. Match the pin numbers molded on your old relay/socket. Typical 4-pin layout uses 85 & 86 as the coil/control side and 30/87 as the load/power side (verify on your part). Before final install, you can bench-test: apply 12V across 85–86 and listen/feel for a click, then check continuity between 30 and 87. Common mounting is a vehicle fuse/relay box or an auxiliary relay socket; make sure terminals are fully seated and the socket is clean/tight to avoid heat. If your application needs a diode/resistor relay, confirm that requirement in the vehicle manual before swapping.
• Fitment note (no guesswork): this listing is for OE# ZTV4/012-1H. Because relay applications vary by vehicle and circuit, confirm fitment by OE number, the wiring diagram in your vehicle manual, and the markings on the original relay (voltage, amp rating, pin count, and terminal numbering) before purchase. Search terms you may see: ZTV4 012-1H / ZTV4-012-1H, and related family codes such as ZTV4/012-1Z or ZTV4/024-1H—only replace if voltage and pinout match your original part.
• Complementary parts for a cleaner repair/upgrade: a 4-pin relay socket/pigtail (6.3mm terminals) is often replaced together when the old socket shows heat damage, loose tension, or corrosion. For add-on circuits, pair with an appropriately rated fuse/holder and proper wire gauge, and follow the vehicle wiring diagram so the relay is triggered by the correct low-current control signal.
