Megger RCDT310 RCD Tester

The low-cost entry-level RCDT310 model is suitable for use on supplies between 100V and 280V, and offers 0.5I, I and 5I tests, with provision for tests starting at 0?/180? of the supply waveform, as well as for DC tests. It also has facilities for testing standard and selective RCDs, and covers current ranges from 30mA to 500mA. When connected to a live supply, it defaults to voltmeter mode. Even if they are inadvertently connected to a live three-phase supply, RCD testers in Megger’s RCDT300 range remain undamaged, and present no safety hazard to the user. Introduced after extensive customer research into the requirements of electrical contractors, these innovative instruments combine rugged construction with straightforward operation, and they are offered at very competitive prices. FEATURES Tests standard, DC and selective RCDs. Ramp testing. Auto (Remote) testing. 3 Phase safe. Enables testing on 110 V centre tapped supplies. Weatherproof to IP54.
