Wago 274-4203 3 Pole Modular Through Connector – Pack of 100
The Wago 274-4203 modular through connector provides 3 separate potentials and four conductor connections per pole, giving 12 clamping units in a white housing. Its lever-operated Push-in CAGE CLAMP® connections accommodate various copper conductor types within the specified limits. This product is supplied as a manufacturer box of 100 connectors.
3 Pole 4-Conductor Connector – 24A
With a 24A IEC rated current, 450V nominal voltage and 4kV rated impulse withstand voltage, this 2.5mm² Wago inline lever connector is designed for organised modular electrical connections. The 3 separate poles have no integrated PE contact.
Push-in CAGE CLAMP® Lever Technology
Solid copper conductors from 0.2–2.5mm² and fine-stranded copper conductors from 0.2–2.5mm² are supported. Suitable solid or ferruled conductors can be pushed in directly; levers provide convenient termination and removal. Other conductor types and ferrule sizes must follow the manufacturer’s stated limits.
Modular Installation
The 274 Series interlocking modules can be combined into custom terminal strips. M3 screw mounting, compatible locking pins, commoning jumpers and strain relief accessories provide flexible installation options. Accessories are available separately. Do not use step-down commoning from 4mm² to 2.5mm² modules.
