ERT3EGREY IMO Screw Clamp Terminal 2.5mm, 300V, 24A, Triple Deck

Why Choose the IMO ERT3EGREY 2.5 mm² Triple Deck Terminal Block with Earth?

The IMO ERT3EGREY is a compact 2.5 mm² triple-deck screw-clamp terminal block with integrated protective earth, designed for high-density industrial control-panel wiring. Its three feed-through levels plus earth connection allow several circuits to be terminated within a single 6 mm-wide terminal position, reducing the amount of DIN rail space required.

Designed for 35 mm DIN rail, the ERT3EGREY uses reliable screw-clamp connection technology and accommodates both solid and stranded conductors from 0.2 to 4 mm². The integrated earth connection uses the mounting rail as the protective conductor, providing a convenient PE connection alongside the three feed-through levels.

The ERT3EGREY is rated at 24 A and has a 300 V cRUus rating for AWG 24–12 conductors, while IMO also specifies 440 V / 24 A / 2.5 mm² under EN 60947-7-1. Its multi-level construction makes it particularly suitable for actuator, sensor, control and distribution circuits where compact, clearly organised termination is required.

Key Advantages

• Triple-deck construction maximises wiring density on the DIN rail.
• Includes an integrated protective-earth connection.
• Rated for 24 A industrial control and distribution circuits.
• 2.5 mm² nominal cross-section with conductor capacity up to 4 mm².
• Only 6 mm wide, helping conserve valuable control-panel space.
• Reliable screw-clamp termination for solid and stranded conductors.
• Designed for standard 35 mm DIN rail.
• Three feed-through levels plus earth provide four connection paths within one compact terminal.

High-Density Multi-Level Wiring for Industrial Control Panels

Multi-level terminal blocks allow panel builders to place several independent electrical connections into the DIN rail space normally occupied by a single conventional terminal. The ERT3EGREY combines three feed-through circuits with a protective-earth connection, making it particularly useful where control signals, power connections and PE conductors need to be grouped together efficiently.

Its 6 mm width and 35 mm DIN rail mounting help increase terminal density without sacrificing conventional screw-clamp termination. The broad 0.2 to 4 mm² conductor range also provides flexibility when integrating the terminal into machinery, actuator circuits, automation panels and industrial distribution systems.

Typical Applications

• Industrial control panels.
• Actuator wiring and distribution.
• Machine control systems.
• Factory automation equipment.
• PLC input and output wiring.
• Sensor and instrumentation circuits.
• Junction and marshalling boxes.
• High-density DIN rail terminal strips.
