Safety information | TheMCS – MULTI CONNECTION SYSTEMincludes 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.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 |
