CSD-CA1G1-1 Johnson Controls Current Switch

Overview

The Johnson Controls CSD-CA1G1-1 is a professional-grade clamp/split core current switch engineered for non-intrusive current detection and motor control in commercial and industrial HVAC applications. Featuring an integrated command relay, this self-powered device monitors electrical current flowing through a cable while facilitating the starting and stopping of the connected motor, making it an efficient solution for building automation systems without requiring an external power supply.

Features

• Split core design allows for easy, non-invasive installation around existing conductors without interrupting the circuit.
• Integrated SPST normally open command relay enables simultaneous current monitoring and motor control.
• Adjustable setpoint threshold offers precise control over trip points for flexible application tuning.
• Dual status LEDs provide instant visual status confirmation of off and on conditions.
• Self-powered operation draws power directly from current induced by the monitored conductor line.
• Solid-state digital output ensures long-term reliability with no moving parts to fail.
