Megger RCDT310 RCD Tester

Overview

The Megger RCDT310 is a dedicated residual current device (RCD) tester for confirming that RCDs in a low-voltage installation trip correctly and within the required time. It performs the standard ½I, I and 5I tests at rated sensitivities of 30, 100, 300 and 500 mA, on both standard and selective (time-delayed) devices, giving electricians a fast, reliable check during inspection and commissioning.

Part of Megger’s RCDT300 range, the RCDT310 also measures supply voltage and provides clear pass/fail-oriented results on a large display. With a rugged CAT III 300 V design, compliance with EN 61557 and up to 2000 tests per set of batteries, it is a dependable everyday tool for contractors and inspectors. (Higher models RCDT320 and RCDT330 add ramp testing, auto-sequences and, on the RCDT330, on-board memory with USB download.)
