Wago 5-contact terminal 221-415 for fine-stranded conductors 0.14–4 mm²

Wago 5-contact terminal 221-415 for fine-stranded conductors 0.14–4 mm² is a compact, push-in style electrical connector that accommodates five conductors in a single module. It is designed for quick, tool-free insertion of fine-stranded wires and maintains secure contact without the need for screw tightening. The terminal is intended for use in control panels, distribution blocks and other installations where multiple conductors must be joined or distributed in a space-saving arrangement.

Advantages

The terminal enables fast and reliable connections of fine-stranded conductors with a rated cross-section range from 0.14 to 4 mm², providing consistent electrical contact and reduced installation time due to its push-in connection mechanism. Its compact footprint allows efficient use of panel and enclosure space, and the five-contact format simplifies wiring runs by combining multiple conductors in one unit. The screwless design reduces the need for tools and maintenance tied to screw loosening over time.

Suitable for

• Control panels and PLC wiring
• Distribution blocks and branch connections
• Signal and low-voltage power wiring
• Machine and equipment internal wiring
• Retrofit and maintenance work requiring rapid conductor changes

Key specifications

• Number of conductor positions: 5
• Supported conductor type: fine-stranded conductors
• Conductor cross-section range: 0.14–4 mm²
• Connection method: push-in (tool-free)
• Compact modular housing for space-saving installation

How to use

Prepare conductor ends by stripping insulation to the manufacturer-recommended length for secure insertion. Insert each fine-stranded conductor directly into the corresponding port until it seats firmly; no screw tightening is required. To remove or reposition a conductor, follow the manufacturer's removal procedure—typically using the specified release tool or by pulling while actuating the release if provided. Ensure power is disconnected before performing installation or maintenance and verify each connection with a pull test or appropriate measurement where applicable.

Usage recommendations

Use the terminal within its specified conductor cross-section range and with fine-stranded wires to ensure reliable contact. Avoid using conductors outside the indicated size range or solid-only conductors unless compatibility has been confirmed. Observe standard electrical safety practices: de-energize circuits before wiring, confirm correct conductor stripping length, and verify connections visually and mechanically after installation.
