D0-system switch disconnector Doepke

Fuse-switch-disconnectors disconnect and also switch under load to protect the system against overcurrent and short-circuit. Tytan II series devices are main fuse switch-disconnectors for D01 and D02 fuses. Simultaneous isolation of all phases is ensured by the screwcap-less plug-in technology. In contrast to the earlier screwcap technology, in which perfect contact could not be guaranteed, the mechanics of the series prevent the formation of high transitional resistances and therefore minimise thermal dissipation power. This design of fuse switch-disconnector with empty housing has a monitoring unit for the fuse. This unit detects a fuse failure and indicates the status using two potential-free signal relays as well as a LED on the front of the unit. The monitoring ensures three-phase operation and therefore provides additional protection for three-phase motors. for example. Disconnectors in the empty housing are supplied with fitted cartridges for fuses up to 63 A. The cartridges can be replaced with coloured cartridges adapted to suit the rated current. The empty housings accept either fuse plug sets with mechanical or flashing display. Plug sets with mechanical displays indicate a faulty fuse in the viewing window and plug sets with flashing displays indicate a faulty fuse with a flashing LED. Properties: low current heat losses; suitable for fuses D01 and D02; finger and back-of-hand proof; large clamping area; Mounting: quick fastening to mounting rail; Einbaulage aufrecht auf der Tragschiene; Application areas: The components are suitable for use in power supplies to residential and purpose-built buildings as well as industrial facilities; Hints: All empty housings are supplied with fitted cartridges that can accept fuse plugs up to 63 A. These are not included in the scope of delivery. Fuse plugs and fuses are available in our fuse plug sets.
