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.
Code No. LIT-12012403
Issued September 2017
The fixed setpoint Current Switch Device for
Electronically Commutated Motors (CSDECM) Series
of Current Switch Devices feature a range of minimum
turn-on options including 250 mA, 350 mA, and
500 mA. These options eliminate the possibility of a
false reading. Even when idle, ECMs draw a small
amount of current. Some fixed point sensors feature a
minimum turn-on value within the vicinity of the ECM’s
idle current, making them ineffective in distinguishing
between on and off status.
CSDECM Current Switch Devices can also be used
with other electrical loads when a simple sensor is
needed.
Features and Benefits
• 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 (CSDSC switch only).

Operation
The CSDSC and CSDECM Current Switch Devices
have an N.O. output (1.0 at 30 VAC/VDC). The output
on the CSDSC switch closes when the monitored
current exceeds 70% full load amps and opens when
the current falls below 60% full load amps, making the
loss of load detection permissible without calibration.
The output on the CSDECM switch closes when the
monitored current exceeds the indicated minimum
turn-on amps; it remains open when falling below the
same threshold.
