How it Works


  • The Coil-Lock allows critical power processes and elements to stay active during power disturbances; Thus, keeping relays, contactors, and motor starters engaged.
  • Voltage Drops can occur from variables outside of a company’s control like Utility System Faults, Motors Starting, Load Variation, and Weather Conditions.
  • The Coil-Lock reduces and minimizes the likelihood of these uncontrolled variables to interrupt business machines and processes equipment by protecting AC relay, contactor, and solenoid devices during a voltage drop.
  • Any device that is controlled by energizing an AC coil, when powered through a Coil-Lock will remain latched through power disturbances.
