The PA30B digital three-phase leakage current tester is specifically designed to detect the leakage current between the power supply terminal and the protective grounding terminal of three-phase three wire/four wire electrical appliances.
And the limit value can be pre-set, with sound and light alarms.

Main technical parameters:

Measurement range 0-2-20mA ± 3%
Alarm value any value within 0-20mA
The measurement time for each phase is continuously adjustable from 1 to 60 seconds
Test voltage 0-450V continuously adjustable (three-phase)
Output capacity of 3/6/9/15kVA and various specifications (three-phase)
Switching mode: manual or automatic commutation

Measurement method:
Alternating phase interruption - or continuous phase interruption
(For phase A shell, phase B shell, and phase C shell respectively)
Two measurement methods
