상품 특징

• Specs & Cross-Refs — Type: 4-pin SPST-NO (Form 1A); coil 12VDC; contact rating up to 80A @14VDC; mini-ISO plug-in terminals; sealed cover. Series coding decodes as: NVF4-3 (family), A=1A, S=sealed, 80=80A, a=plug-in. Compatible cross codes within the same family: NVF4-3A-Z80a (dust-cover), NVF4-4a-S80a (with bracket). Always match coil voltage and bottom-view pin layout.
• Install & Location — Seats into a standard mini-ISO 4-pin socket (JD2912 style). Usual locations are engine-bay fuse/relay boxes or interior junction blocks. Disconnect battery, confirm 30/87 (load) and 85/86 (coil) on the bottom-view diagram, press fully into the socket until locked, then function-test per service manual.
• Compatibility Check — Use when the original relay is marked NVF4-3A-S80a or an equivalent mini-ISO 4-pin, 12V coil, Form 1A part with identical socket pattern. Match the bottom-view numbering (30/87/85/86) and 12V coil; this ensures fit across vehicles/equipment that specify a 4-pin SPST-NO 80A relay.
• What It Fixes / Typical Uses — Restores switching in high-load circuits commonly assigned to 4-pin Form 1A relays: engine cooling fan, fuel pump, headlamps/aux lamps, A/C compressor clutch or blower, ABS power feeds, and general power distribution where a NO contact is required.
• Complementary Parts (for related slots) — 4-pin relay socket/harness: JD2912-1H; 5-pin changeover counterpart if your slot needs SPDT: NVF4-3C (Form 1C); bracketed variant for bolted mounts: NVF4-4a. Select by contact form (1A vs 1C), coil voltage (12V), and the same mini-ISO footprint.
