Megger LRCD220-FR Loop Impendence & RCD Combined Tester, Loop Impedance Test Type 2 Wire 500V, RCD Test Type AC, DC, RCD

Megger Loop Impedance and RCD Combined Tester, 10mA to 1000mA RCD Test Current Range, Armoured Rubber Case - LRCD200 Series - LRCD220-FR

Make sure your electrical safety systems are in top-notch condition with this loop impedance and RCD combined tester from Megger. Its no-trip feature means you can check all devices over 30mA without accidental activation. The handy instrument can also read the trip time of your RCD to ensure it reacts quickly to fault currents, with an auto-test function letting you focus on the breaker during the process. For additional peace of mind, you can perform 2-wire fast testing, phase-to-phase and phase-to-earth measurements on this versatile device.

Features & Benefits

• RCD test current range of 10mA to 1000mA gives you a broad scope
• IP54 rating demonstrates protection against water sprays for a weatherproof unit
• Integrated voltmeter lets you read voltage levels
• Backlit display for convenient viewing in low-light settings

Applications

• Electrical engineering
• Security systems
• Control panels
• Lighting fixtures

How does earth loop impedance testing work?

Testers like this one measure the impedance of the electrical loop by releasing a test current to the circuit. This tells you if the system can deliver enough current to activate the fuse in case of electrical faults and disconnect quickly enough to prevent a fire outbreak.
