FAQ
-
What is this socket/base used for?
It's the DIN-rail or panel-mount base that a compatible pluggable relay plugs into — the socket carries the field wiring terminals while the relay itself can be unplugged and swapped without disturbing the wiring.
-
Which relays is this compatible with?
Check the Technical Specifications table and the model code for the exact matching relay range (e.g. ABB's CR-M or CR-P pluggable relay series) — sockets and relays within the same range are designed to be interchangeable.
-
Can I install this myself?
The socket itself can be DIN-rail clipped in easily, but wiring it into a live control panel should be done by a licensed electrician or qualified panel builder.
-
Does the socket come with the relay?
No — this is the socket/base only, sold separately from the plug-in relay. Confirm you're ordering both parts if you don't already have a compatible relay or socket.
