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
