Omega WDU Type A
Omega WDU Type A is a withdrawable unit with a position indicator and moving control unit. Our withdrawable units (WDU) have high operational safety and have IP20 Protection in all positions. The units can rate up to 630A, 500kw, 690V, and can hold up to 20 units per section. The WDU’s can be put in a test position and they are fully re-configurable while live which ensures minimal downtime. The outgoing cables are connected to outlets or terminals in the cable section, so the units can be switched out or fixed easily.
Auxiliary cables
The auxiliary cables are connected to terminals in the cable section, which can be accessed from the rear or the front. To guarantee the safety of the WDU’s, an optional Logstrup or Harting coding system depending on plug configuration is available, which ensures that the units are placed correctly in the switchboard. The Units have a Mechanical interlock on the disconnector shaft and key.
Microswitches
The optional microswitches make it possible to change between isolated, test, and connected position. The units can connect with different communication systems such as DeviceNet and Profibus. 4 dedicated positions achieved by physical movement of the unit: – Removed position – Isolated position (padlocking possible) – Test Position (padlocking possible) – Connected position Sizes: X = 3, 4. Y = 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4 Type of electrical connections (acc. To IEC 61439-2) : W W W
