ABB CR-M4SS Standard Socket for CR-M Interface Relays

The CR-M4SS is a standard socket from ABB's CR-M miniature relay range, designed to accept CR-M interface relays with either 2 c/o or 4 c/o (SPDT) output contacts. Fitted with screw connection terminals and suitable for DIN rail mounting, it forms the base for building compact, serviceable relay assemblies in control panels across UAE commercial and industrial installations.

Key Features

  • Compatible with both 2 c/o and 4 c/o CR-M miniature interface relays for flexible panel design
  • Screw connection terminals rated at 250V and 7A for reliable, serviceable wiring connections
  • Compact footprint suited to space-constrained control cabinets and relay banks
  • Accepts optional pluggable function modules, holders, and markers for expanded functionality
  • Genuine ABB quality — rated for operation from -40°C to +70°C

  • Interface relay socket applications in BMS and industrial control systems

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.
