CSDECM-C35200L2 Johnson Controls Current Switch

Overview

The Johnson Controls CSDECM-C35200L2 is a fixed setpoint Current Switch Device designed for Electronically Commutated Motors (ECMs) and other electrical loads. It features a clamp-on (split-core) design that allows for easy installation in tight enclosures without disconnecting the monitored lines, providing reliable verification of equipment operation. By incorporating a low turn-on threshold, it effectively distinguishes between an ECM’s idle current and its true operational status to prevent false readings.

Features

• Clamp-on style split-core design fits easily into tight mechanical enclosures
• Monitored load induces operating power directly from the conductor, eliminating the need for an external power supply
• Low turn-on current expands utilization down to sub-fractional horsepower motors
• Polarity-insensitive output provides straightforward, error-free wiring
• Fixed setpoint avoids the need for live calibration or specialized personal protective equipment during setup
