10 UniGear ZS1: type ZVC switchgear for motor switching and control Each unit is equipped with a withdrawable vacuum contactor with fuses. The use of medium voltage protection fuses strongly limits the let-through fault energy, making it possible to reduce the cross-section of the connection cables to the motor. This characteristic contributes to safeguarding the insulation levels and increasing the electrical life of the cables and of the machine connected. For users with high consumption levels, it is possible to fit the contactor with two fuses in parallel for each of the phases. The units can be coupled directly with the main switchgear, with the possibility of extension on both ends. Studied to offer Configurable for all types of motor starting Drastic reduction in the width of the switchgear and of the surface area occupied (the typical unit is 325 mm wide), also using more than one contactor for complex motor start-ups The same service and maintenance procedures as the UniGear type ZS1 switchgear Full access from the front Typical motor start-ups: direct, reversal of direction, reactor, autotransformer, star delta Electrical characteristics Typical unit cross-section Rated voltage kv Rated insulation voltage kv Rated power frequency withstand voltage kv 1min Rated lightning impulse withstand voltage kv Rated frequency Hz Rated short time withstand current ka (3s) Peak current ka Internal arc withstand current ka 1s ka 0.5s Main busbar rated current A Branch connection rated current A Unit width mm Unit height mm 2200/ /2595 Unit height with gas duct mm Unit depth mm E D A E B D A Height Height with gas exhaust duct Single-line diagram of the main typical units C C 1 2 Depth Width A Apparatus D Instruments B Main busbar E Gas exhaust duct C Feeder 3 Off 1 Contactor with electrical latching 2 Contactor with mechanical latching 3 Two pole transformer for supply of operating circuits Standard components Accessories Alternative solutions 10
