CSDSC Current Switch Devices
Description
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 preset the sensor eliminates the need for Personal Protective Equipment (PPE) that is required by OSHA when working with a live panel.
Refer to the CSDSC and CSDECM Current Switch Devices Product Bulletin (LIT-12012403) for important product application information.
Features
CSDSC Current Switch Devices
• Split and Solid Core Models with Mini-Sized Variants—Fit in tight enclosures.
• Monitored Load—Supplies power without a power supply.
• Optional N.O. Relay—Adds 10 A at
125 VAC switching power with a choice of
24 or 12 V coil.
• Polarity Insensitive Output—Provides easier wiring.
• Low Turn on Current—Extends use to sub-fractional HP motors.
• LED Indication of Switch Status—Allows you to easily check the switch’s on/off status.
