1. Applicabilityn 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 4000A, 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 number of units and panels required.

Features
2. Safety designn 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 interlocksThe 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 drawn-out or inserted.(3) When IEC298 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 isin [SERVICE] position.

2. BusbarsThe busbars are of hard-drawn high-conductivity copper, and can be insulated with epoxy-coating except connections. The connections are covered with easily removable insulated cover.The insulations can withstand a rated voltage for 1 minute as well as a temperature rise caused by short-circuit currents.
Busbar compartment DK8746
3. Voltage Transformers (VTs)The VTs are epoxy resin molded type. The VTs and its associated primary fuses are withdrawable type, and are installed in the independent compartment. The VTs have the "service" and "disconnected" positions with a indicator visible from the outside of the unit.

Application Guide of Surge AbsorberThe high surge voltage by the VCB 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.

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 current, 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.
