Automatic Circuit Shutdown Device (ACSD)
Series Circuit Monitor

Monitor your circuits for trouble automatically

Our ACSD series circuit monitoring device is designed to monitor your circuit for undercurrent, overcurrent or arcing. If a problem is detected, the ACSD will disconnect power to your oil switch or contactor after a preset time delay. The circuit will remain locked out until the ACSD is reset by repair crews.

Using the ACSD can prolong the life of your circuit by switching off power in the event of an electrical arc, open circuit or failed regulator. It can detect arcs in air, underground or under water.

ACSD is the most comprehensive series circuit monitoring device on the market.
