CLSB

CLAMP-ON CURRENT SENSOR

Functions & Features
•Easy-to-install, spring-loaded, clamp-on type current sensor
•Over-voltage clamp element for safety in open circuit
•Wide frequency band
•Screw terminal connection

MODEL: CLSB–[1]

ORDERING INFORMATION
• Code number: CLSB-[1]
Specify a code from below for [1].
(e.g. CLSB-05)
Confirm the correct sensor type described on the data sheet of the combined transducer/transmitter module.

[1] INPUT
R5: 5 A
05: 50 A
10: 100 A
20: 200 A
40: 400 A
60: 600 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.

Caution 1: The output values may vary depending on the accuracy of engagement at the clamp connection.
Caution 2: The sensor’s mechanical construction may cause it to generate resonance sound. However, it does not affect the perfomrance of the sensor.
