Features & Types
Salient Features
Low Voltage Vacuum Contactor and Medium Voltage Vacuum inductive switching over voltages
Contactor Comes with smart & ready to use Voltage Control Card – Less
Wide range - Rated Voltage 415V-12kV, Rated Current upto 1000A, control wiring & improved Customer Convenience
STC upto 10kA for 1Sec., AC-4 Duty Compliant Very high reliability due to minimum no. of dynamic components in
VC with higher BIL i.e. PFHV-38kVrms & Impulse-95kVp available VC Mechanism
for high altitude requirements High mechanical and electrical life & Low maintenance
Flexibility to configure VC in case of change in control voltage even Rugged structure for higher reliability in harsh dusty-corrosive
at site without changing control coils atmosphere
Option for selecting No. of Poles i.e. 1/2/3 & Latching Mode i.e. In-House R&D enables continuous improvement & development of
Electrical / Mechanical, for specific applications like Neutral VC
Grounding, Soft Starters etc. Fully Type Tested
Epoxy Encapsulated VI Pole enables Higher Insulation & makes VC Certified with latest QMS (ISO 9001-2008), EMS (ISO 14001-
Compact & Cost effective to integrate 2004) & OHSAS (BS 18001-2007)
Low chopping current – No requirement of surge suppressor for VCs compliant to latest IEC: 60947 & IEC 62271-106

Note:
1. VCs are suitable for INDOOR application only 4. MVVC Closing Coils are NOT suitable for continuous Rated control Voltage
2. Use of separate phase barriers for 3-Pole MVVC is must 5. VC Aux Contacts are NOT suitable for DC breaking. Hence DO NOT use for coil
3. MVVC Coils are suitable for DC control supply only. Bridge Rectifier or VCC is current breaking
required for AC control supply at site 6. Dimensions above are indicative. Specific GAD to be referred before engineering
