Vacuum Contactor Technology

A "Vacuum Contactor" is a "Switching device" that "makes and breaks"

the electrical current inside a chamber called "Vacuum Interrupter Tube"

(VI).

A Vacuum Interrupter is a sealed-off device with a level of vacuum

>10-5 torr.

VI. At current zero the arc ceases & the circuit voltage is isolated

contacts.

The special contact material used in the VI, ensure low chopping current

& switching over voltage, thus enhances the life of connected load. Viz.

Motors, Transformers, Capacitors etc.

Salient Features

Vacuum Contactor and Medium Voltage Vacuum

Contactor

Wide range - Rated Voltage 415V-12kV, Rated Current upto 1000A,

STC upto 10kA for 1Sec., AC-4 Duty Compliant

VC with higher BIL i.e. PFHV-38kVrms & Impulse-95kVp available

for high altitude requirements

Flexibility to configure VC in case of change in control voltage even

at site without changing control coils

Option for selecting No. of Poles i.e. 1/2/3 & Latching Mode i.e.

Electrical / Mechanical, for specific applications like Neutral

Grounding, Soft Starters etc.

Epoxy Encapsulated VI Pole enables Higher Insulation & makes VC

Compact & Cost effective to integrate

Low chopping current - No requirement of surge suppressor for

inductive switching overvoltages

Comes with smart & ready to use Voltage Control Card - Less

control wiring & improved Customer Convenience

Very high reliability due to a minimum no. of dynamic components in

VC Mechanism

High mechanical and electrical life & Low maintenance

Rugged structure for higher reliability in harsh dusty-corrosive

atmosphere

In-House R&D enables continuous improvement & development of

VC

Fully Type Tested

Certified with latest QMS (ISO 9001-2008), EMS (ISO 14001-

2004) & OHSAS (BS 18001-2007)

VCs compliant to latest IEC 60947 & IEC 62271-106
