CSDECM-C35200L1 Johnson Controls Current Switch

Overview

The Johnson Controls CSDECM-C35200L1 is a fixed setpoint Current Switch Device designed for Electronically Commutated Motors (ECMs) and other electrical loads. It provides reliable verification of equipment operation by distinguishing between true operational status and the small idle currents typical of ECMs, preventing false readings. Featuring a clamp-on design, it includes an integrated normally open sensing relay for fail-safe switching in building automation and HVAC systems.

Features

• Split-core/clamp-on design fits into tight enclosures
• Fixed setpoint eliminates live calibration, saving installation time
• Low minimum turn-on current of 0.35 A prevents false readings from ECM idle current
• Self-powered monitored load operation requires no external power supply
• Integrated SPST-NO relay provides straightforward circuit switching
• Polarity-insensitive output simplifies field wiring
