ERPE50 IMO Screw Clamp Earth Terminal 50mm

Why Choose the IMO ERPE50 Screw Clamp Earth Terminal?

The IMO ERPE50 is a heavy-duty 50 mm² protective earth feed-through terminal block designed for reliable earthing connections in industrial control panels, power distribution equipment and machinery. Part of IMO's standard screw-clamp terminal range, it provides a robust connection between protective-earth conductors and the mounting rail.

Designed for 35 mm DIN rail, the ERPE50 features screw DIN rail fixing, a closed terminal construction and a flat cable entry. Its substantial conductor capacity makes it particularly suitable for higher cross-section protective-earth wiring where smaller terminal blocks cannot accommodate the required cables.

The ERPE50 has a nominal cross-section of 50 mm², accepts solid conductors from 16 to 70 mm² and stranded conductors from 25 to 50 mm². It provides IP20 protection, is identified as a PE terminal and is designed for mounting on MR35 × 7.5 mm DIN rail.

Key Advantages

• Heavy-duty 50 mm² protective earth terminal for industrial installations.
• Screw-clamp connection provides secure termination of large conductors.

High-Capacity Protective Earth Connections for Industrial Panels

Large industrial electrical systems often require substantial protective-earth conductors to provide an effective low-impedance path between equipment and the installation earthing system. The ERPE50 is designed specifically for this role, accommodating large conductors while providing a secure screw-clamp connection and direct protective-earth interface through the DIN rail mounting system.

With its 50 mm² nominal cross-section, 20 mm width and capacity for conductors up to 70 mm², the ERPE50 provides panel builders and machine manufacturers with a practical solution for high-capacity PE termination. Its green/yellow identification and closed construction also help maintain clear, organised and readily identifiable protective-earth wiring.
