Wago terminal connector 4‑pole 0.5–2.5 mm² 24 A 400 V

Wago terminal connector 4‑pole 0.5–2.5 mm² 24 A 400 V is a compact plug‑in connector engineered for making secure electrical connections in confined spaces. It accepts conductors from 0.5 to 2.5 mm² and is rated for continuous currents up to 24 A and system voltages up to 400 V. The connector’s low‑profile housing and reliable contact mechanism provide vibration resistance and consistent electrical performance in control panels, junction boxes and domestic installations.

Advantages

The 4‑pole Wago terminal offers a compact footprint and plug‑in convenience that speeds up wiring and maintenance tasks. Its clamping system ensures a secure connection across the supported conductor range without the need for tooling for most conductor types. Designed for repeated insertions and removal, the connector maintains contact reliability under vibration and thermal cycling. The transparent or semi‑transparent housing option facilitates visual inspection of conductor insertion and termination quality.

Suitable for

• Control cabinets and industrial distribution blocks
• Junction boxes and branch connections
• Residential electrical installations and lighting circuits
• Temporary or modular installations requiring quick replacement

• Current rating: 24 A
• Voltage rating: 400 V
• Connection type: plug‑in terminal with spring/clamp contact
• Housing: compact, low‑profile for space‑saving installations
• Mechanical characteristics: vibration resistant, designed for repeated mating cycles

How to use

Strip the conductor to the recommended length for the connector and, where applicable, bend or shape the conductor end to suit the insertion method. Insert the conductor into the appropriate pole until it seats firmly against the stop; ensure that insulation is not inside the clamping area and that the conductor is visible through any inspection window if present. For multi‑core connections observe correct polarity and phase sequence. When removing conductors, follow the manufacturer’s procedure for unclamping or actuator operation to avoid damaging the conductor or the contact element.

Recommendations

Use the connector within its rated current and voltage limits and select conductor sizes within the specified range. Verify that the conductor insulation stripping length matches the connector’s requirement and inspect terminations visually after assembly. Avoid exceeding the torque or mechanical stress limits described in the manufacturer’s technical documentation. For circuits with higher environmental or safety requirements consider additional protective measures such as enclosures or strain reliefs.
