Short Description:

Kyoritsu RCD Testers KEW 5410 key features:

Measurement of RCD trip time
Conducting testing of rated residual non-operating currents at
× 1/2 Range, measuring RCD trip time at × 1 and × 5 Ranges.
• Measurement of trip out current
Measuring trip out current by varying current automatically.
• Remote Test
Enabling a user to hold the Test Leads with his both hands
by locking the Test Button. Measurement will automatically
start when the main voltage is detected.
• Voltage Measurement
Carrying out a constant measurement of voltage in the
stand-by mode at each Range.
• Auto-detection of Contact voltage
Detecting the voltage to earth of Earth electrodes or
Protective conductors during RCD test – when applying
test currents – at measurement using EARTH in order to
prevent electrical shocks caused by the damaged earth.
Measurement will be ceased at AC50V or more.
• Dust- and Water-proof
Dust- and Water-proof construction
(designed to IEC 60529 IP54).
• Backlight
Facilitating working at dimly illuminated locations.

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.
