ACI 117853 Mini Fixed Current Switch Split Core 0-150A

The ACI 117853 (Model A/MSCS) is a mini fixed current switch designed for AC current monitoring applications where reliable on/off status indication is required. This compact split-core current switch provides a simple "go/no-go" monitoring solution for fans, pumps, motors, and other electrical equipment.

Key Features:

• Split-core design allows installation without disconnecting conductors
• Operating range: 0 to 150 amps AC
• Fixed trip point: 0.55A or less
• Normally open (N/O) solid-state switch output
• Contact rating: 0.5A @ 36 VAC/VDC
• Aperture size: 0.53 inches (accommodates up to 1 AWG wire)
• Non-polarity sensitive output for AC and DC loads

This current switch features a solid-state switching output suitable for interfacing with building management systems and control panels. The split-core design opens for easy installation around existing conductors without circuit interruption. Recommended for use with 16-22 AWG shielded cable or twisted pair wiring, with maximum wire runs under 98 feet. When controlling motors or fans, an additional contactor is required due to the 0.5A output rating. Backed by ACI's 5-year limited warranty.
