RCD Testers

RCD testers verify that residual current devices (earth leakage circuit breakers) trip within the correct time and current limits, helping electricians confirm that installations are properly protected against electric shock and earth faults. We carry 100% authentic RCD testers from Kyoritsu and Uni-T, backed by manufacturer warranty. As an authorized distributor, Techno Tools & Equipment offers competitive pricing and fast delivery across Malaysia, with same-day delivery for Klang Valley customers.
