WAGO Rail-Mount Terminal Blocks

Installation accessories:

End plate/middle plate: 2-4mm thick, used for end sealing of terminal block groups to enhance mechanical stability.

DIN rail: 210 series, 35x7.5/15mm specification, steel/copper material, galvanized treatment, corrosion-resistant.

Snap on mounting feet: 209-123 series, suitable for panel installation, with a spacing of 35-40mm.

Installation and wiring operation specifications

1. Key requirements for wiring

Conductor processing:

Stripping length: 8-23mm (depending on the series, such as micro terminal block 8-9mm, high current terminal block 16-23mm).

Multi strand conductor: Cold pressed terminals (216 series) are required, otherwise one size larger terminal block should be selected.

Aluminum conductor: After cleaning the surface oxide layer, apply "Alu Plus" contact paste to prevent oxidation and electrolytic corrosion.

Wiring steps:

CAGE CLAMP ®： Insert the tool into the rectangular opening → Open the fixture → Insert the conductor → Pull out the tool lock.

Push-in CAGE CLAMP ®： Solid/multi stranded conductors with ends inserted directly; Other conductors need to be inserted with tools tilted into the opening and unlocked before insertion.

2. Installation precautions

Spacing requirement: Reserve 20mm on both sides of the terminal block group, and reserve 35-65mm above and below to ensure heat dissipation.

Grounding requirements: In hazardous voltage scenarios, DIN rails must be grounded (PE) to ensure electrical safety.

Explosion proof scenario: Select Ex i certified models and reserve creepage distance as required (e.g. 4 distance modules need to be connected after Ex i module).

Typical application scenarios and configuration schemes

1. Industrial control circuit

Configuration: 280 series straight through terminal block+281 series fused terminal block+769 series pluggable terminal block.

Advantages: Control circuit overload protection, quick insertion and removal during maintenance, signal and power partition wiring.

2. Motor wiring

Configuration: 283 series high current terminal block+281 series double-layer terminal block+grounding terminal block (green and yellow).
