If the load is less than 16 amps and single pole switching is OK then these relays and sockets from Finder are ideal. ( image is two pole, single pole is the same appearance )

There is a single pole rated at 16 amps and double pole rated at 10 amps.

Word of caution, some relays have contacts on 3mm pitch and other have 5 mm pitch, you need to check carefully that you have the correct socket for the selected relay.

• Fitted into a small consumer unit. I cannot find the right image. They can be purchased without the main switch, they are then called an enclosure

A consumer unit is more expensive than a din rail enclosure and has a gaping great hole in the front. Those finder relays are not suitable for that enclosure. These would suit a consumer unit enclosure.

I have taken on board a comment about the "exposed" terminals.

Using a DIN socket and plug in relays allows for easy replacement of a relay, DIN rail mounted relays ( without sockets ) requires work on the wring to the relay.
