ACI A/CS Series A/CSX Series Solid-Core Fixed Current “Status” Switches

Solid-Core Fixed Current “Status” Switches
A/CS Series A/CSX Series

The A/CS and A/CSX series current switches are available in a solid-core with either Normally-Open (N/O) or Normally-Closed (N/C) output configurations. All of these sensors will have a solid-state output with a fixed trip point (setpoint). These current switches are ideal for providing status information on any type of AC current using equipment. The A/CS and A/CSX current switches are accurate, reliable, easy to install, and require less servicing than differential pressure switches, flow switches, and paddle wheels.

These current switches should be used in applications in which a “Go/No Go” current switch is required. A change in the operating current may indicate mechanical failure or that the unit has been turned off. The A/CS and A/CSX series current switches can be used to monitor devices with a maximum continuous operating current of up to 250 Amps.

These current switches will not need to be externally powered, since the power for the switch is induced from the conductor being monitored. Another great feature of the A/CS and A/CSX series current switches is that they include a Red “Status” LED that will indicate whether the current is above or below the fixed trip point.
