CSW Solid Core and Split Core Current Switches 1-200A

The CSW series of AC current switches activates a normally open (NO) contact when the monitored primary circuit current exceeds a preset level via a solid-state switch. Models are available to switch various load types, feature integral LEDs to indicate device power and switch status, and can be provided in solid or split-core configurations. The CSW-Axx models include a multi-turn adjustment to set the trip threshold to the desired value, while the CSW-Fxx models operate as a go/no-go status indicator with a factory-set minimum threshold. The switches can continuously monitor up to 200 Amps and feature an auto-range circuit to eliminate the need for manual jumpers.  All models are UL, CE, and RoHS compliant. The CSW series current switches are accurate, reliable, easy to install, and require less servicing than differential pressure switches or flow switches.  The CSW series current switches can be used to monitor devices with a maximum continuous operating current of up to 200 Amps, and the power supply is induced from the monitored conductor.
