CSDSC-C50150L0 Johnson Controls Current Switch

Overview

The Johnson Controls CSDSC-C50150L0 is a self-calibrating, clamp-on split-core current switch designed to provide reliable verification of electrical equipment operation. It features a single-turn dial to select motor full load amps, eliminating the need for live calibration and reducing installation time by allowing setup while the panel is de-energized.

Features

• Split-core clamp design allows for easy installation in tight enclosures without disconnecting cables.
• Single-turn dial for simple preset calibration without requiring personal protective equipment.
• High, low, and power LED indicators provide immediate visual validation of switch status.
• Induced power from the monitored conductor cable removes the need for an external power supply.
• Polarity-insensitive output simplifies integration with building control networks.

Specifications

• Current Range: 0.50 A minimum trip setpoint value to 150 A maximum current.
• Switch Setpoint: Adjustable via manual dial.
• Status Output: Normally open (N.O.) switch, rated at 1.0 A at 30 VAC/VDC.
• Sensor Supply Voltage: Induced from the power conductor cable.
• Frequency Range: 50/60 Hz.
• Operating Temperature Range: 5 to 140 degrees Fahrenheit (-15 to 60 degrees Celsius).
• Humidity Range: 0 to 95% noncondensing.
• Wire Size: 14 to 24 AWG.

Applications

• Monitoring electrical loads to confirm performance in commercial HVAC applications.
• Verifying the status and runtime proof of ventilation fans, exhaust fans, and circulating pumps.
• Integrating with building automation systems for proof-of-flow and load loss detection.
