3 PHASE ELCB TESTER MODEL - 6221 EL
The 6221 EL is a 3-Phase Presence and Rotation Indicator combined with a 3-Phase Industrial Earth Leakage Tester.
When utilized as a 3-Phase Presence and Rotaton Indicator, the instrument does not use the batteries. Therefore, it can still be utilized if the batteries are not present or if the batteries are too low.
The 3-Phase Presence and Rotation Indicator portion of the 6221 EL,takes its power from te circuit under test.
The Earth Leakage portion of the tester can be utilized on either a Single-Phase Powered System (up to 317Vac Line-to-Earth)or a 3-Phase Powered System (550V Line-to-Line or Phase-to-Phase) with a protective Earth conductor.The Earth Leakage tester required batteries.When utilized on a single phase, ensure a correct connection between Line and Earth before using the tester.
