It's a relay, possibly ex GPO one.
If I agreed with you, we'd both be wrong

Very similar to a Post Office 3000 type relay fitted with contact spring guards.

The CuS on the label may be an indication that it is fitted with a copper slug to make it either slow operating or slow release, depending on which end of the coil the slug is fitted.

A view from above and front would be good, just out of interest.

More BT than GPO. The wire colours we used were Blue, orange, green, brown and slate and mixtures of these, blue/white, orange/white, green/white etc. plus blue/orange, blue/green, blue/brown, blue/slate then orange/green, orange/brown/orange/slate etc. Slate was of course grey but was called slate because grey and green start with the same letter.

Says BT on the label.

I've seen similar relays for sale at about 25p.
