2 Features 1. Applicability n VCM-CLAD has a high applicability as a switchgear for various industrial facilities and power plants with its wide range ratings (up to 12kV, up to A, up to 50kA). The suitable system can be made a plan by the wide selection. n VCM-V3, V6 A maximum of up to three units can be stacked so allowing a drastic reduction in the of units and panels required. Scope of basic type 2. Safety design n VCM-CLAD is designed for horizontal isolation, and the unit housing is of firm fabricated-steel construction. n The metal-clad design of VCM-CLAD ensures safety with perfect interlocks. The withdrawable circuit breaker has complete mechanical interlocks to prevent a mal-operation. n Busbar and circuit spout orifices are fitted with automatically operated safety shutters. The shutters are of resin, and close orifices by withdrawal of the breaker. 3. Safety interlocks The following mechanical interlocks are provided to achieve safety. (1) The circuit breaker cannot be drawn-out or inserted to/from the service position while it is closed. (2) The circuit breaker cannnot be closed while it is being drawnout or inserted. (3) When IEC28 standard (Metal clad type) is applied, aux. circuit plug interlock is provided as shown below. Aux. circuit plug can not be removed while the circuit breaker is in [SERVICE] position.

7 Application Guide of Surge Absorber The high surge voltage by the that injures the insulation of the machines and apparatus is generated under certain specific conditions. The necessity of surge protection depends on the dielectric strength of the device used as a load. The application guide given below is based on the results of switching surge tests. When the dielectric strength of the device is low, use of a surge absorber is recommended. g Surge absorber application guide Load Voltege 3.3kV 6.6kV 11kV Rotating machine Molded transformer *1 *2,*3 (BIL 45kV) *2,*3 (BIL 60kV) *3 or gapless arrester (BIL 55kV) Oil-immersed *2,*3 transformer *1 (BIL 45kV) Dry-type *3 transformer *1 (BIL 25kV) *2,*3 (BIL 60kV) *3 (BIL 35kV) *2,*3 (BIL 0kV) *3 or gapless arrester (BIL 55kV) Notes : Protection device required : Protection device not required *1 : The withstand voltages (impulse) of transformer must exceed the values listed above. *2 : When interrupting a magnetizing inrush, it is recommended that a protection device be used. A standard lightning arrester is sufficient. *3 : Semiconductor device must be provided with suitable protection devices when a semiconductor is installed on the load side of transformer, since a surge on the low voltage side will also cause a voltage appear on the load side, depending on the turns ratio.
