Limitamp Air to Vacuum Conversion

Limitamp Air to Vacuum Conversion

Limitamp Vacuum Contactors are designed to provide long, trouble-free service with only a minimal amount of maintenance. At the same time, this new generation of contactors makes the system safer for workers, helping reduce arc flash energy.

A conversion from an air to vacuum contactor switches the operation from an AC closing coil to a DC closing coil, which, even if misaligned, will not vibrate or chatter and, consequently, will not cause system wear.

Air to vacuum upgrades are available for IC7160 Limitamp and ITE 7850 applications.

  • No need for exhaust chutes
  • No replaceable arc vanes and arcing horns to maintain
  • Uses same clip and bolted fuses as air break contactors
  • Long life with minimal maintenance
