Why Choose the IMO ERT3GREY 2.5 mm² Triple Deck Terminal Block?
The IMO ERT3GREY is a compact 2.5 mm² triple-deck screw-clamp terminal block designed for high-density industrial control-panel wiring. Its three-level construction allows multiple independent circuits to be terminated within a single DIN rail position, helping panel builders reduce terminal-strip length while maintaining clearly organised connections.
Designed for standard 35 mm DIN rail, the ERT3GREY uses proven screw-clamp connection technology for secure termination of solid and stranded conductors. The terminal accepts conductors from 0.2 to 4 mm², making it suitable for a wide range of control, signal, instrumentation and low-power distribution circuits.
The ERT3GREY is rated at 24 A and has a 300 V cRUus rating for AWG 24–12 conductors. IMO also specifies a 440 V, 24 A, 2.5 mm² rating to EN 60947-7-1, making this compact triple-level terminal a versatile choice for industrial machinery and automation installations.

High-Density Triple-Deck Wiring for Industrial Control Panels
Multi-level terminal blocks allow several independent circuits to occupy the DIN rail space normally required by a conventional single-level terminal. The IMO ERT3GREY provides three feed-through levels, making it particularly useful for applications involving groups of related signal, control or low-power conductors.
Its combination of triple-deck construction, 24 A current rating and 0.2 to 4 mm² conductor capacity provides flexibility for machinery and automation wiring. Conventional screw-clamp termination also makes the terminal straightforward to integrate into established panel-building practices and maintenance procedures.
Typical Applications
- Industrial control panels.
- Machine control systems.
- Factory automation equipment.
- PLC input and output wiring.
- Sensor and actuator circuits.
- Instrumentation and signal wiring.
- Junction and marshalling boxes.
- High-density DIN rail terminal strips.
