CSDECM-C35200L4 Johnson Controls Current Switch

Overview

The Johnson Controls CSDECM-C35200L4 is a fixed setpoint Current Switch Device designed specifically for Electronically Commutated Motors (ECMs) and other electrical loads. It effectively distinguishes between motor on and off statuses by utilizing a specific minimum turn-on threshold, overcoming the challenges associated with the idle current draw typical of ECMs. Featuring a clamp-on design, this switch allows for straightforward installation and integration into building automation and energy management systems without necessitating conductor disconnection.

Features

• Clamp-on core design facilitates easy installation without disconnecting existing electrical lines.
• Low minimum turn-on threshold prevents false status readings caused by standby or idle ECM current.
• Monitored load architecture supplies operational power to the device directly from the conductor, eliminating the need for an external power supply.
• Integrated relay option expands capability, supporting robust switching power for external equipment.
• Polarity-insensitive output structure simplifies wiring tasks for technicians.

Specifications

• Monitored Current Range: Up to 200 A maximum
• Minimum Turn-On Amps: 0.35 A (350 mA)
• Output Configuration: Normally Open (N.O.), 1.0 A at 30 VAC/VDC
• Relay Contact Rating: 10 A at 125 VAC
• Core Type: Clamp-on / Split-core
• Wire Size Compatibility: 14 to 24 AWG
• Operating Temperature Range: 5°F to 140°F (-15°C to 60°C)
• Operating Humidity Range: 0% to 95% non-condensing

Applications

• Monitoring operational status for Electronically Commutated Motors (ECMs) in commercial HVAC setups.
• Verifying run-status for building automation systems (BAS) controlling fans, pumps, and compressors.
• Integrated equipment monitoring circuits requiring reliable, non-calibrated loss-of-load detection.
• General electrical load monitoring within industrial control panels and energy management systems.
