Mounting holder for Wago 221 Series 4 mm² connectors on DIN-35 rail, orange (Wago 221-500)

Mounting holder for Wago 221 Series 4 mm² connectors on DIN-35 rail, orange is a dedicated rail adapter that allows Wago 221 4 mm² push-in connector modules to be fixed securely to a standard 35 mm DIN mounting rail. The holder provides a stable mechanical connection between connector modules and the rail, allowing neat, space-efficient installation of connector blocks in distribution boards, control cabinets and junction boxes. Its orange color assists in visual identification and circuit organization when multiple connector rows are present.

Advantages

The mounting holder delivers reliable mechanical retention for Wago 221 Series 4 mm² connector modules while preserving access to the push-in terminals. It supports quick installation on standard 35 mm DIN rails and enables orderly arrangement of multiple connector modules. The bright orange finish improves visibility for quicker identification and reduces wiring errors. The adapter is compact, minimally increases module footprint, and facilitates service access and replacement without rewiring.

Suitable for

• Fixing Wago 221 Series 4 mm² push-in connector modules to 35 mm DIN rails in distribution boards
• Organising terminal rows in control cabinets and automation panels
• Mounting connector blocks in junction boxes where DIN-rail mounting is used
• Applications requiring visual circuit identification or color-coded grouping

Key specifications

• Compatibility: designed for push-in connector modules with 4 mm² conductor capacity from the corresponding series
• Mounting type: snap-on for standard 35 mm DIN mounting rails
• Material: durable insulating plastic suitable for electrical enclosure use
• Color: orange for visual identification and grouping
• Form factor: slim profile to minimise occupied rail space

How to use

Attach the mounting holder by snapping it onto the 35 mm DIN rail at the required position, ensuring the clip engages the rail securely. Insert the compatible Wago 4 mm² connector module into the holder until it seats firmly; verify that the push-in terminals remain accessible for conductor insertion and that the module is stable. When removing or replacing modules, depress the appropriate release points and lift the module clear of the holder to avoid disturbing adjacent wiring.

Usage recommendations

Use the orange holders to group related circuits or mark dedicated lines for easier maintenance. Confirm compatibility with the 4 mm² connector version before mounting and ensure installations comply with applicable electrical standards and cabinet clearances.
