• Compatible with most automation and control systems
• One output represents the current in each phase
• Externally Powered - Simple and reliable connection
• Designed for longest life and reliability
• Sensing windows provide ample space for single or multiple conductors per phase
• Snap onto DIN rail or attach with screws to a panel for secure mounting

AT/ATR-TH Series Current Transducers are the latest innovation for monitoring three-phase loads, motors, machines or buildings. The large triple-aperture solid-core design allows for a quick and easy installation. Just thread the conductors through the sensing windows (apertures) and reconnect on the other side. The AC current transducer outputs are powered from an excitation voltage of 24 VAC or DC, or optionally 120 VAC, isolated from the monitored circuit. Three outputs are proportional to the AC current in each phase and a fourth represents the average of the three. Each are available at any time. The relay mounts on a back panel or a DIN rail and is designed to accommodate wire sizes for loads up to 200 amps.
