ORDERING INFORMATION
• Code number: CLSA-[1]
Operational range & overload capacity
(Operational range: Overload capacity)
Specify a code from below for [1].
(e.g. CLSA-08)
CLSA-08: 80 A maximum 120 A continuous
CLSA-12: 120 A maximum 300 A continuous
CLSA-30: 300 A maximum 360 A continuous
CLSA-50: 500 A maximum 600 A continuous
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.
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
INSTALLATION
CAUTION
Operating temperature: -10 to +55°C (14 to 131°F)
Operating humidity: 30 to 90 %RH (non-condensing)
Mounting: Fix with a binding strap.
Weight
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.
