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.
Other versions (or variants) can be requested from WAGO Sales or
