ACI Split Core Adjustable Current Switch 0.70 to 150A

The A/MCS-A and A/MSCS-A are N/O solid state adjustable current switches. These current sensors are ideal for providing status information on any AC current using equipment. The A/MCS-A series is excellent for new installations where the conductors can be run through the housing before connecting the wires.
The A/MSCS-A switches are ideal for retrofit applications, since their split core design allows them to be opened and clamped around the existing wires without disconnecting the current being monitored. Both of these units do not need power supplied to them as they induce the current from the conductors being monitored.
The A/MCS-A and A/MSCS-A both have outputs that are non-polarity sensitive N/O solid-state contacts for switching both AC and DC circuits up to 36 volts. These switches also include two Status LED indicators that will indicate three states: tripped on, current present but below trip point, and current off or below the low end of the adjustable trip point range.
The A/MCS-A and A/MSCS-A adjustable current switches can be used to monitor any change in AC current. A change in current may indicate motor failure, belt loss/slippage, or mechanical failure. Any time one of these events occurs, the current can significantly decrease, thus tripping the current switch and immediately notifying the Building Management System of the failure or problem.
