Description Functions Motorised Sircover VE are remote controlled tri or tetrapolar switches. They are a combination of two back-to-back, interlocked remote-operated disconnecting switches. They switch, reverse or toggle between two low voltage power circuits on load and provide safety isolation. Conformity To Standards IEC 60947-3 EN 60947-3 BS EN 60947-3 NBN EN 60947-3 VDE 0660 part 107 General Characteristics 3 stable positions (I, O, II) or on request overlapping contacts (I, I+II, II). Possible automatic switching from one to the other on load (AC-22 and AC-23). Fully visible breaking or isolation. Dry contact electrical position control. Manual emergency operation. Locking in 3 positions. Available On Request Special remote-control voltage. Devices with visible breaking on position I. Devices with overlapping contacts I, I+II, II. Devices with 6/8 poles. Devices with different ratings between position I and II for strong current. Devices for by-pass applications. Specifications Rated insulation voltage: 1000 V. Rated impulse withstand voltage: 12 kV. Overload capacity: 50 to 55 A.
