The Carrier Fixed “Status” Current switches are designed for use in any AC current monitoring application in which you are looking for a “Go/No Go” or On/Off status for a particular piece of equipment. The current switches should be installed on the line side of the power to the motor, pump, compressor or other equipment. The current switches are available in both solid and split-core versions which also includes a Patented 35 mm Din Rail mounting foot for easy installation in panel mount applications. The solid-core versions are a great choice for new installations or OEM applications in which cost sensitivity, lower trip points and environmental issues may be of concern.

Note: The Fixed Current Switches are not intended to be used in Life / Safety applications or in Hazardous / Classified locations.
