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.

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.
