IntelliVAC Features
 A wide range of supply voltage (110 – 240 V AC 50/60 Hz, 110 -
250 V DC) allows implementation in multiple applications
 Consistent vacuum contactor pick-up time (at a given supply
voltage) ensures repeatable performance
 Selectable vacuum contactor drop-out time improves coordination
with upstream power fuses
 Electronic altitude compensation (400 A only) eliminates
mechanical compensation required for altitudes above 1,000
meters (800 A contactors include a user-friendly altitude
adjustment)
 Power loss ride-through (TDUV) allows the vacuum contactor to
remain closed during short power loss (may require an optional
external capacitor, dependant on ride-through time)
