The 6221 EL is a 3 Phases Presence and Rotation Indicator combined with a 3 Phases Industrial Earth Leakage Tester. This instrument represents the quickest and easiest way for servicing, repairing and electrical maintenance of 3 phase system with earth leakage.
● Microprocessor-controlled.
● Very low consumption.
● Indicates: Phase rotation & Phase presence (does not require battery to indicate).
● Phase presence indication from as low as 100Vac.
● Tests for disconnection Sensitivity / Time.
● Indicates battery status.
● Measures voltage phase to earth.
● Select one of 3 Phase to test ELCB.
● Color-coded test leads.
● Over-Temperature Protection (Referenced to Earth).
● Phase Polarity Trip Indicator (Referenced to Earth).
● Fused earth leakage tester.
● Led indication of Voltage on ELCB.
