This Tyco mini relay runs a 24V coil with change over contacts so you can swap a circuit between normally open 30A and normally closed 40A outputs using standard 5-pin wiring. You can drop it into small fuse boxes or tight engine bays where a full-size relay will not fit and still handle solid current for lights compressors or other gear on 24V setups. Inside the case you get silver contacts sized for those 30A and 40A ratings so the relay keeps resistance low when the amps climb. The coil is resistor protected which helps control voltage spikes in 24V looms and protects switches and control modules. A removable metal bracket lets you bolt the relay to a guard rail or panel then unclip it if you want to shift the layout later. Handy little unit and a smart buy for tidy wiring.

• Compact housing ideal for crowded fuse panels

Q: Is this relay suitable for continuous duty use?

Yes it is rated for continuous duty use. That means the coil can stay energised for long periods without overheating under its specified 24V rating. This suits applications like running work lights beacons or other loads that may stay on for hours. You still need to keep current within the 30A and 40A contact ratings.

Q: What does resistor protected mean on this relay?

The coil circuit includes a built in resistor to reduce voltage spikes when the relay switches. Those spikes normally feed back into the control side and can stress switches or electronics. The internal resistor helps manage that energy within the relay body. You get neater wiring as there is no need to add a separate resistor across the coil.

Q: Can I use this relay in place of a standard 4 pin relay?

Yes if your wiring allows for the extra contact and pin. This relay uses a 5-pin change over format with both normally open and normally closed outputs available. If your original relay only used a single output you can wire just the contacts you need. Always match the coil voltage at 24V and stay within the current rating.

Q: How is this relay normally mounted in a vehicle?

The relay includes a removable metal mounting bracket for simple fitment. You can bolt the bracket to a guard panel bar or relay rack using a single screw or bolt. The relay body then clips into the bracket for support. Many setups also plug the 5 pins into a relay base to keep wiring organised.
