Description |
Main switch characteristics including positive drive to IEC/EN 60204 and VDE 0113. Isolating characteristics to IEC/EN 60947-3 and VDE 0660. N switch-disconnectors can, in addition, be combined with NZM...-XU, NZM...-XA shunt releases and auxiliary contacts as well as with NZM...-XR... remote operator. For DC switching, all 4 contacts must be connected in series. Refer to the information on jumper kit accessories. When working with ungrounded systems (e.g., IT), the installation must ensure that a double ground fault will be impossible. Switch can not be combined with plug-in/withdrawable units and/or connection on rear. Within the scope of application for UL489B, the switch cannot be combined with connection width extensions, module plates, or band terminals either. N4-4-...-S15-DC feeder unit and outgoer from the bottom only. Suitable for 100%-rated application together with an enclosure with minimum dimensions of 1200 x 600 x 275 mm (WxHxD). Does not provide any overcurrent protection. |
