Details
3 Phases Industrial Earth Leakage Tester
Select One of 3 Phase to test RCD or ELCB / Indicates Phase Rotation
Model: 9221B
Introduction:
• This Test Instrument is a combined 3 Phases Presence and Rotation Indicator combined with a 3 Phases Industrial Earth Leakage Tester.
• When utilized as a 3 Phase Presence and Rotation Indicator,the instrument does not use the batteries and can still be utilized if the batteries are not present or if the batteries are too low.
• The 3 phase Presence and Rotation Indicator which is inside the 9221B, takes it's power from the circuit under test.
• The Earth Leakage can be utilized on a Single Phase (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 requires batteries.
• When utilized on a single phase, ensure correct connection between Line and Earth before using the tester.
• When utilized on a 3 Phase Powered System, the instrument is then utilized as a 3 Phases Presence and Rotation Indicator and a Earth leakage tester (selecting which phase to Earth will be utilized for the RCD test).
• When utilized on a 3 Phases Powered System, this instrument is a rotary field indication instrument which display all three phases by lighting up it's corresponding Lamp. It display the rotation (clockwise or anti-clockwise) on a LED.
• To test the tripping time or the tripping current of a Earth Leakage Circuit Breaker, make sure to connect the earth wire.
• This instrument represents the quickest and easiest way for servicing, repairing and electrical maintenance of 3 phase system with earth leakage.
• With this equipment, you can, before connecting Load to Supply: On the supply side; Quickly verify the presence of the three Phases on a 3 Phases Power System.
• Confirm the Phase Rotation on a Powered 3 Phase System. Test the Tripping (disconnection) current and time of the protections.
Features:
• Indicates Phase Rotation.
• Indicates Phase Presence.
• TEST for Disconnection Sensitivity.
• Indicates Battery Status.
• TEST for Disconnection Time.
• Measure Voltage Phase to Earth.
• Select One of 3 Phase to test RCD or ELCB.

• Very Low Consumption.
• Fused Earth Leakage Tester .
• Lightweight, Robust & Compact.
• ELCB Works 50Vac to 330Vac 50Hz / 60Hz.
• Led indication of Voltage on ELCB.
• Phase Rotation and Presence does not require battery to indicate.
• EN 61010-1 CAT III 550V. EN 61326-1
