Chauvin Arnoux C.A 740N Voltage Tester P01191741Z Data Sheet

22

The C.A 740N is a Voltage Detector with indicator lights.

It complies with the requirements of standard IEC 61243-3.

The main function of the C.A 740N is to test for the absence of 
any voltage. It detects hazardous voltages, meaning voltages 
exceeding the ELV (extra low voltage: 50 V

ac

 or 120 V

dc

), 

even if its batteries are low or missing.

Its other functions are:

 

„ Indication of a voltage between 12 and 690 V

ac

 or 750 V

dc

, 

with indication of the polarity.

 

„ Continuity indication.

 

„ Indication of the phase position.

The voltages indicated on the C.A 740N are nominal volt-
ages. Make sure that the device will be used on networks at 
standardized voltages.
