CSD-CA1G0-1 Johnson Controls Current Switch

Overview

The Johnson Controls CSD-CA1G0-1 is a Current Switch Device (CSD) Series digital output current switch designed to non-intrusively detect AC current flowing through a cable or wire. This self-powered, split-core model features an adjustable trip setpoint, making it a cost-effective solution for monitoring the on/off status or proof of operation for electrical loads without requiring an external power supply.

Features

• Split-core design allows for easy installation around existing wires without disconnecting them
• Adjustable trip setpoint ranging from 1.25 A to 135 A
• 100% solid-state output with no moving parts to fail, ensuring long-term reliability
• Polarity-insensitive output simplifies wiring to building automation controllers
• Dual status LED indicators provide clear local visual monitoring
• Completely self-powered operation induces power directly from the monitored line
• Compact size fits easily in tight mechanical enclosures and includes a snap-in mounting bracket
