Description
Kyoritsu 5410 RCD Tester
The Kyoritsu KEW 5410 is a tester for residual current devices or RCDs, that is used to assess and gauge the functionality of ground fault circuit interrupters, or GFCIs. An RCD is a type of electrical safety device that guards against electric shock by sensing and breaking a circuit as soon as a leak or current imbalance is detected.
An RCD is a safety mechanism that senses an imbalance between live conductors and automatically cuts off the electrical supply. The device tracks the current differential between the active and neutral conductors in a single-phase circuit.
The total current in the line and neutral conductors is zero in a healthy circuit, meaning that there is neither protective conductor current nor fault current flowing to Earth. Thus, some of the line conductor currents will not return through the neutral conductor in the event of a line-to-earth fault.
Accurate and Reliable RCD Testing for Professionals
The KEW 5410 RCD Tester is an essential tool for electricians, safety inspectors, and engineers who need fast and accurate residual current device (RCD) testing. Designed to ensure electrical safety compliance, this tester quickly detects RCD trip times and trip currents, helping prevent electrical hazards. Whether testing in residential, commercial, or industrial settings, the KEW 5410 delivers precise, repeatable results, making it a trusted choice for professionals worldwide.
When the residual current reaches a predetermined limit, known as the “residual operating current,” the RCD operates, monitors this difference, and disconnects the circuit. The Kyoritsu 5410 assesses this. Buy RCD Testers from mme-ae at affordable prices.
A Complete Electrical Testing Solution
The KEW 5410 isn’t just an RCD tester—it’s a comprehensive solution for electrical safety testing. Whether you’re verifying installation integrity or diagnosing potential leakage currents, this device streamlines your workflow. Complement it with optional accessories like the Model 7121B test lead for distribution boards, ensuring that your testing kit is fully equipped to meet diverse regulatory standards and deliver dependable, professional results every time.
