THE new RCDT310 and RCDT320 Megger earth leakage breaker testers available from Power Parameters bring a new dimension in user convenience.
Both instruments permit the testing of RCDs with ratings of 30, 100, 300, and 500mA at 1/2, rated, and 5 times rated current at 0 and 180 degrees.
The Megger RCDT 320 also has an automatic cycle test as well as a ramp test. Touch voltage is measures at the start of the test with test inhibit user-selectable at 25 or 50V. Large, numeral digital readout LCDs provide clear unambiguous data to the user.
The Megger RCDT testers are provided with blown fuse indication and are three-phase safe. A safety interlock shutter prevents incorrect application of test leads.
Clearly colour-coded switches permit easy identification of tests and the instruments are designed for industrial environments having sturdy cases with thick rubber bumper strips.
