The coil uses resistor suppression (680 ohm), which helps reduce coil kickback without forcing a polarity on the coil connections.\u003c\/p\u003e\u003cp\u003eThe relay has an IP54-rated housing, a black body, and an integrated mounting bracket, so it can be secured in a protected electrical area that sees vibration and occasional splash, but not direct washdown or standing water.\u003c\/p\u003e\u003ch6\u003eKey features\u003c\/h6\u003e\u003cul\u003e\n\u003cli\u003eNominal 12V coil with up to 18V max coil voltage; pick-up at 8.0V or less and drop-out at 1.3V or more\u003c\/li\u003e\n\u003cli\u003eCoil resistance 100 ohm (plus or minus 10%), with resistor suppression for non-polarized coil wiring\u003c\/li\u003e\n\u003cli\u003e50A continuous switching capacity on the normally open contact, with inrush capability up to 200A (lamp) or 150A (motor)\u003c\/li\u003e\n\u003cli\u003eFast response with operating and releasing times up to 10 ms\u003c\/li\u003e\n\u003cli\u003e4-pin Mini ISO layout with standard relay terminal numbering (85\/86 coil, 30 feed, 87 switched output)\u003c\/li\u003e\n\u003cli\u003eBlade terminals sized 6.3 x 0.8 mm (85\/86) and 9.5 x 1.2 mm (30\/87), plus bracket mounting for a secure installation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch6\u003eElectrical and system integration\u003c\/h6\u003e\u003cp\u003eTerminal 30 is the high-current feed, terminal 87 is the switched output, and terminals 85 and 86 power the coil. Because the load tabs are larger (9.5 x 1.2 mm), confirm your relay socket or crimp terminals are the correct size and rated for the current you are running.\u003c\/p\u003e\u003cp\u003eOn a 12V boat, this relay is commonly used to let a dash switch, breaker panel switch, or electronic controller trigger a larger load such as deck and spreader lights, a horn, pumps, or other accessories. Protect the feed to terminal 30 with the right fuse or breaker for the wire and the load, and keep the high-current run short to reduce voltage drop.\u003c\/p\u003e\u003ch6\u003eInstallation and placement on board\u003c\/h6\u003e\u003cp\u003eUse the mounting bracket to fasten the relay to a bulkhead, under-helm electrical panel, or inside an enclosure where it stays accessible for inspection. IP54 handles splash and dust, but it should still be kept out of bilges and away from areas that stay wet or get hit with a hose.\u003c\/p\u003e\u003cp\u003eIf the circuit has a heavy startup surge, confirm the load is within the relay’s inrush limits and that your wiring and connections stay cool under load.\u003c\/p\u003e\u003ch6\u003eWho it fits\u003c\/h6\u003e\u003cp\u003eThis relay is a solid match for 12V systems that need straightforward on\/off control of a single higher-current circuit from a small control signal, especially when you want a bracket-mounted Mini ISO relay rather than a loose plug-in cube.\u003c\/p\u003e","brand":"Hella Marine","offers":[{"title":"Default Title","offer_id":52269009273013,"sku":"QBP513750","price":14.4,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0977\/8171\/1029\/files\/1298668_qbp513750.jpg?v=1771541444","url":"https:\/\/www.qualityboatparts.com\/products\/qbp513750","provider":"Quality Boat Parts","version":"1.0","type":"link"}
