Why Choose the IMO ER4WHITE Screw Clamp Terminal?
The IMO ER4WHITE is a compact 4 mm² single feed-through screw clamp terminal block designed for secure conductor termination in industrial control panels, electrical cabinets and automation systems. Part of the IMO ER series, it provides a robust and serviceable connection using proven screw-clamp technology and mounts directly onto standard TS35 DIN rail.
The ER4WHITE features a compact 6 mm terminal width, helping engineers build high-density terminal assemblies without unnecessarily consuming valuable DIN-rail space. Its white insulating housing provides clear visual identification, while captive screws, integrated wire stops and finger-safe wire entry help simplify installation and servicing.
Rated at 600 V and 30 A with a conductor range extending to AWG 10, the ER4WHITE is suitable for demanding industrial wiring applications. Under IEC 60947-7-1 specifications, the ER4 family is rated at 750 V and 32 A with a nominal cross-section of 4 mm².

Reliable Terminal Connections for Industrial Control Systems
The IMO ER4WHITE uses a proven screw-clamp mechanism to create secure mechanical and electrical conductor connections. Captive screws remain retained during installation, integrated wire stops help prevent excessive conductor insertion, and the screw-clamp design incorporates protection against loosening in environments where machinery and electrical equipment may be exposed to vibration.
Its single feed-through configuration provides a straightforward connection between incoming and outgoing conductors, making the ER4WHITE suitable for structured terminal strips in control cabinets and machinery. The compact TS35 DIN-rail format also allows multiple ER4 terminals to be installed alongside compatible end plates and jumper accessories for efficient industrial circuit distribution.
Typical Applications
- Industrial control panels and electrical cabinets.
- Distribution boards and junction boxes.
- Machine control and automation systems.
- PLC and instrumentation wiring.
- Industrial power and control circuit distribution.
- Factory automation and production machinery.
