ATC Diversified AC-301-440 Three Phase 430-480V Phase Loss Monitor

ATC Diversified, AC-301-440, Three Phase 430-480V Line Under Voltage and Phase Loss Monitor

Features:

• The three-phase lines for adverse conditions such as Phase Loss, Under Voltage, and Phase Reversal (improper sequence).
• They will also detect a Power Failure or Thermostat Interruption. When any of the mentioned occur, the control relay drops out.

When the fault has been corrected, the delay-on-make delay period begins. This delay is field adjustable from 0.2 to 8 minutes. It is incorporated to allow the head pressure to equalize before restart. It provides random restart in multiple equipment installations.
