AC CURRENT TRANSDUCER
(clamp-on current sensor; RMS sensing)
Functions & Features
• Converts an alternating current into a standard
process signal
• Easy-to-install clamp-on type current sensor
without needing a current transformer
• Clamp-on current sensor included
• Wide input range from 10 A up to 600 A
• Input frequency 50 / 60 / 400 Hz
• Over-voltage clamp element for safety in open
circuit
• High-density mounting
Typical Applications
• Centralized monitoring and control of motors at
a supervisory panel
• Monitoring abnormal load current at motors to
detect pump malfunctions
600: 0 – 600 A AC (Not selectable with the sensor type
code 1 'Leadwire type CLSA')
