CLSA

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.
