A plug-and-play socket for heavy-duty mini relays rated 60 to 80A, with slots for both 4-pin and 5-pin layouts. Grips the relay body firm so it stays put under engine-bay vibration. Fits aftermarket wiring on 4WDs, caravans, boats and trade utes, anywhere a relay runs driving lights, electric fans, fuel pumps, horns or auxiliary circuits.

Takes relays with 9.5mm by 1.2mm flat spade pins, the standard heavy-duty mini pattern (not the thinner 6.3mm micro). The body is high-temp nylon with sprung brass contacts behind each pin cavity. Comes with five crimp terminals that accept 1.5 up to 6mm² cable, enough to wire a full 5-pin relay without buying extras.

The socket itself is passive, so the relay's own contact rating sets the ceiling. Match a 60A relay to loads up to 60A continuous and a 80A relay to loads up to 80A continuous. Fuse the trunk feed at the source and crimp the terminals properly before pressing them home; a loose pin will arc and melt the socket before the fuse ever sees the fault.

A relay socket for 60–80A heavy-duty mini relays with 9.5mm × 1.2mm pins.
12V and 24V DC vehicle systems: 4WDs, utes, caravans, boats, trucks
4-pin and 5-pin heavy-duty mini relays
Micro relays with 6.3mm × 0.8mm or 4.8mm × 0.8mm pins (cavities won't grip)
Standard mini ISO relays with the smaller 6.3mm pins (use a mini ISO socket instead)
240V AC mains, strictly DC automotive relay use

Q: What does "heavy-duty mini" actually mean?
It's a mini ISO relay with thicker 9.5mm × 1.2mm pins instead of the standard 6.3mm × 0.8mm. The thicker pins carry more current without heating up, the reason an HD mini is rated to 60–80A where a standard mini tops out around 40A.

Q: How do I know if my relay fits this socket?
Measure the pin width across the flat face. 9.5mm wide pins go in this socket. If the pins measure 6.3mm or 4.8mm, you need a different socket (either a mini ISO or a micro socket).

Q: Does the socket itself limit current, or does the relay?
The relay's contact rating is the limit, not the socket. Pair a 60A relay with up to 60A loads, an 80A relay with up to 80A loads. The socket is passive copper and nylon.

Q: What's the difference between a 4-pin and 5-pin relay?
A 4-pin relay has one output (normally open). A 5-pin relay has two outputs (one normally open, one normally closed), so you can switch between circuits instead of only turning one on and off.

Q: What wire size do the terminals accept?
The five crimp terminals accept 1.5 up to 6 mm² automotive cable. For a 60A continuous load run 6 mm² on the output legs; for a short-run 80A load, 6 mm² is still enough on legs under 300mm.

Q: Can I use this on a 24V truck or caravan system?
Yes. The socket is passive copper and nylon so it handles 12V or 24V DC equally. The relay plugged into it is what sets the voltage rating, so buy a 24V-coil relay for a 24V vehicle.

Q: Does it come with the relay?
No. Just the socket and five crimp terminals. The relay is a separate purchase; see the 'Pairs with' section above for a matching 80A heavy-duty mini relay in our range.

Q: Do I still need a fuse if I use this socket?
Yes. Fuse the trunk feed at the source (within 150mm of the battery), matched to the relay's contact rating. The socket itself does nothing for fault protection.

Q: What stops the relay vibrating loose?
The pin cavities grip the spade pins by sprung brass contacts. Once pushed home the relay stays put under normal 4WD and marine vibration. A dab of dielectric grease on the pins before fitting helps if it's going into a wet underbonnet install.

Q: Can I run this in a wet area like a bullbar or canopy?
The socket is not IP-rated on its own. For wet installs, mount it inside a weatherproof enclosure or wrap it into a loom with heat-shrink over the pin ends. Do not bolt a bare relay socket to the outside of a bullbar.

Q: How do I pop a terminal out if I crimp one wrong?
Lift the small locking tab inside the pin cavity with a thin pick (an auto-wire removal tool or a flattened staple). The terminal slides back out the wire side. Re-crimp or replace, then push it back in until it clicks.

Q: Can I gang two or more sockets together?
Yes. Most heavy-duty mini sockets snap side-to-side on a rail, so you can gang 2, 3, or 4 next to each other inside a relay box. The side profile on this socket is the standard snap pattern.
