CSDECMM-C50050 Johnson Controls Current Switch

Overview

The Johnson Controls CSDECMM-C50050 is a mini split-core fixed setpoint current switch designed to monitor electrical current and verify proof of operation for Electronically Commutated Motors (ECMs) and other electrical loads. Its high minimum turn-on threshold eliminates false readings from idle motor currents, ensuring reliable status detection for building automation systems.

Features

• Mini-sized split-core design allows for easy installation in tight enclosures.
• Fixed setpoint of 500 mA eliminates the need for live calibration.
• Self-powered device draws its operating energy directly induced from the monitored cable.
• Polarity-insensitive digital output simplifies installation and control wiring.

Specifications

• Status Output: Normally Open (N.O.), 1.0 A at 30 VAC/VDC
• Maximum Current Capacity: 50 A
• Minimum Trip Setpoint Value: 0.50 A (500 mA)
• Aperture Sensing Hole Size: 0.4 x 0.32 inches (10.2 x 8.1 mm)
• Frequency Range: 50/60 Hz
• Operating Temperature Range: 5 to 140 degrees F (-15 to 60 degrees C)
• Isolation Voltage: 600 VAC rms (UL), 300 VAC rms (CE)

Applications

• Monitoring on/off status and proof of operation for sub-fractional HP motors and ECMs.
• Verifying the load status of HVAC equipment such as fans, pumps, blowers, and heating coils.
• Integrating status feedback into control circuits and building automation monitoring systems.
