1.4. C.A 773 IP2X
See § 2.8.
1.5. FUNCTIONALITY
The C.A 773 is a voltage detector with indicator lights.
It complies with the recommendations of the IEC 61243-3 standard.
The main function of the C.A 773 is Voltage Absence Testing (VAT). It detects haz-
ardous voltages, i.e. higher than ELV (extra-low voltage) 50 V
ac
or 120 V
dc
), even if
the device’s batteries are spent or absent.
Its other functions are:
Indicating a voltage between 12 and 1000 V
ac
or 1400 V
dc
with polarity indication.
Indicating the quality of the continuity level.
Indicating the phase position.
Indicating the phase order.
Load switching (controlling the triggering of the 30 mA differential circuit breakers).
The voltages indicated on the C.A 773 are nominal voltages. Ensure that it is used
on voltage-normalized networks.
