ACI ECMCS split-core current switches are designed for use in electronically commutated motor (ECM) applications in which you are looking for status for a particular piece of equipment

  • ECMs have a unique operating profile that includes a small standby current when the motor is powered but not actively spinning compared to no current draw of traditional PSC motors
  • The ECMCS switches do not require external power, since the power for the current switch is induced from the conductor being monitored
  • ACI’s ECMCS switch has an adjustable trip level to set the desired trip level for proper motor status indication in most ECM applications
  • ACI offers a calibration tool that will help assist the installation process by implementing a visual indication of the state of the output switch to the installer
  • The ECM current switch can be secured to the monitored cable using a cable tie and the integrated cable tie anchor feature of the housing
  • The ECMCS switch also comes with an attachable mounting foot that allows the unit to be mounted in any position using one Tek screw or snapped directly on a 35mm DIN rail
  • Note: The ECM switch is not intended to monitor status in VFD motor applications
