Suitable for use with 30, 100, 300 and 500mA RCDs and selective/DC breakers, Megger's RCDT310 provides the user with the ability to test RCDs for correct implementation.
Although the entry-level product in the RCDT300 series, the RCDT310 is highly accurate, easy to use and can perform1/2I, I and 5I testing procedures. It'll also display touch voltage at the start of the test and RCD polarity can also be tested at 0 or 180°.
This unit is designed with safety in mind; the user can set a voltage inhibit which will prevent testing if a large voltage is detected, it is safe for use on 3 phase systems and even comes built inside its own IP54 weatherproof case for extra protection in demanding conditions.
