The Current Switch Devices Self-Calibrating [CSDSC] Series of Current Switch Devices Provide Reliable Verification of Electrical Equipment Operation in a Variety of Applications, Including Fans and Pumps. CSDSC Current Switch Devices Use A Single-Turn Dial to Select Motor Full Load Amps, Eliminating the Need for Live Calibration and Significantly Reducing Installation Time Compared to Traditional Current Switches. CSDSC Switches Use Full Load Amps Instead of Horsepower, Eliminating the Need for Separate Part Numbers as a Function of Line Voltage. CSDSC Current Switches are Installed when the Panel is De-Energized. The Ability to Present the Sensor Eliminates the Need for Personal Protective Equipment [PPE] That is Required by OSHA when Working with a Live Panel.
