Why Choose the ABB CR-M4LP Push-In Logical Relay Socket?
The ABB CR-M4LP is a compact push-in logical relay socket designed specifically for ABB CR-M miniature pluggable relays with four changeover contacts. As part of the ABB CR-M pluggable relay range, it provides a secure mounting and electrical connection interface for relay installations in industrial automation, machinery and electrical control panels.
The CR-M4LP features push-in spring connection terminals, providing fast and intuitive conductor termination without conventional terminal screws. The self-tightening connection technology supports secure wiring and is particularly useful in applications exposed to vibration and shock, while also helping reduce installation time during control-panel assembly.
Designed for 4 C/O (SPDT) CR-M relays, the CR-M4LP uses a logical terminal arrangement with the coil connections A1 and A2 on the lower side and the common, normally open and normally closed contact connections on the upper side. It is suitable for snap-on mounting onto a standard 35 mm DIN rail and accepts compatible pluggable function modules, holders and markers.

Fast and Reliable Relay Wiring
The ABB CR-M4LP provides the electrical and mechanical interface required to integrate compatible four-changeover CR-M relays into industrial control systems. Its push-in spring terminals allow suitable conductors to be inserted directly for a secure connection, helping reduce wiring time and eliminating the need for routine screw-terminal retightening.
The logical terminal layout separates the coil connections from the relay contact wiring to support structured control-panel design. Compatible function modules can be plugged into the socket, while optional holders and markers provide additional installation and identification flexibility for industrial relay assemblies.
Typical Applications
- Industrial electrical control panels.
- PLC and controller interface circuits.
- Machine building and factory automation.
- Relay interface assemblies.
- Process control systems.
- Rail and transportation control equipment.
- Industrial installations exposed to vibration and shock.
