MODEL: CLSA http://www.m-system.co.jp/ CLSA SPECIFICATIONS ES-9282 Rev.6 Page 1/2 CLAMP-ON CURRENT SENSOR Functions & Features

  • Easy-to-install, nylon spring-loaded, clamp-on type current sensor
  • Over-voltage clamp element for safety in open circuit
  • Wide frequency band MODEL: CLSA–[1]

ORDERING INFORMATION

  • Code number: CLSA-[1] Specify a code from below for [1]. (e.g. CLSA-08) Confirm the correct sensor type described on the data sheet of the combined transducer/transmitter module. [1] INPUT 08: 80 A 12: 120 A 30: 300 A 50: 500 A CAUTION Before you remove the sensor module or mount it, turn off the input signal for safety. While the line is alive, the module’s cores, attracted to each other, may be hard to separate.
