CSDECM-C35200L3 Johnson Controls Current Switch

Overview

The Johnson Controls CSDECM-C35200L3 is a fixed setpoint current switch device designed for electronically commutated motors (ECMs) and general electrical loads. Featuring a clamp-on split-core design, it accurately distinguishes between the on and off status of motors by utilizing a low minimum turn-on threshold, effectively eliminating false readings caused by idle standby currents.

Features

• Clamp-on split-core configuration allows for simplified installation in tight enclosures without disconnecting wiring.
• Low minimum turn-on current extends operational compatibility to sub-fractional horsepower motors.
• Monitored load induces operating power directly from the conductor, eliminating the need for an external power supply.
• Polarity insensitive status output provides easier and safer installation wiring.
• Integrated normally open relay adds 10 A at 125 VAC auxiliary switching capabilities.
