4 Each panel con-sists of two superimposed units which are com-pletely independent of each unit can be fitted with either circuit-breakersor contactors, as well as all the accessories avail-able for the traditional switchboard units. All thesignificant components are identical to those usedfor the single-level its middle part, the panel is provided with acompartment to take the auxiliary instruments ofboth the units. A compartment for housing otherinstruments is available in the top part of double-level units can be coupled directlywith the single-level units, and there is the possi-bility of extension on both ends of the switchboard requires access from the rear forinstallation and maintenance procedures,whereas all the service operations are carried outfrom the BTRR M J JMIFIFIFIFIFIFE lectrical characteristicsRated voltageRated insulation voltageRated power frequency withstand volatgeRated lightning impulse withstand voltageRated short time withstand currentPeak currentInternal arc withstand currentMain busbar rated currentsBranch connector rated currents2nd level1st levelIFIncoming/outgoing feederBTBus tieRRiseRMRise with measurementJJoint unitJMJoint unit with measurementTypical unitskVkVkV 1 minkVkA 3 skAkA 1 skA TYPE ZVCUniGear type ZVC has evolved from the in-novative ZVC design and has been fully har-monised into the UniGear unit is equipped with a fused withdraw-able vacuum contactor.

5 For feeders withhigh current, it is possible to fit the contactorwith two fuses in parallel for each of extreme compactness of the switchgear(each unit is only 325 mm wide) is one of itsmain units can be coupled directly with themain switchboard and there is the possibilityof extension on both ends of the to the compact dimensions of theunits and to the possibility of installing theswitchboard against the room walls, the foot-print is notably reduced, even when usingmore than one contactor for complex use of medium voltage protection fuses greatlylimits the fault let-through energy, making it possi-ble to reduce the cross-section of the connectioncables to the motor. This characteristic helps tosafeguard the insulation levels and increase theelectrical life of the cables themselves and of themachine they are connected type ZVC is now a part of the ABB UNIqueair-insulated switchboard to offerWide range of combinations for every type ofmotor starterEfficient use of space for switchboards withnumerous contactor outgoing feedersDrastic reduction in the width of the switchboardand of the overall footprintSame service and maintenance procedures asthe UniGear type ZS1 switchboardFull access from the solution for motor starters, power-factor correctioncapacitor banks and transformer feeders up to kVMulti function circuit configuration.
