Specifications

Notes

• Safety information 1: The MCS – MULTI CONNECTION SYSTEM includes connectors without breaking capacity in accordance with DIN EN 61984. When used as intended, these connectors must not be connected/disconnected when live or under load. The circuit design should ensure header pins, which can be touched, are not live when unmated.
• Variants:: Other pole numbers || Gold-plated or partially gold-plated contact surfaces || Other versions (or variants) can be requested from WAGO Sales or configured at https://configurator.wago.com/
