Learn more by watching our Kyoritsu 5406A | Digital RCD ELCB Tester With Auto Ramp Function video.
The Kyoritsu 5406A is a digital RCD (ELCB) tester rated for single-phase 230V AC operation, built to measure the trip time and trip current of residual current devices. The 5406A runs five test functions, including an auto ramp test, and checks Standard, Selective, Type AC and DC-sensitive Type A devices. It is built to IP54 and complies with IEC 61557 for installation testing.
Confirming that a residual current device trips inside the wiring-rules time limits calls for a dedicated tester, not a plug-in checker. The Kyoritsu 5406A measures real trip time in milliseconds and confirms trip current through its auto ramp function. It covers the 10mA to 500mA sensitivities found on domestic and commercial boards, so one unit handles most jobs.
Set the rated tripping current, plug into the protected outlet, and the 5406A drives test current until the RCD trips. The result holds on the large LCD, and a 0 and 180 degree phase switch returns both best and worst trip times. Three wiring-check LEDs flag reversed phase and neutral before any test starts. Powered from the circuit under test with no battery to go flat, the 5406A stays ready for a one-off check or a full day on the boards.
The Kyoritsu 5406A is built for single-phase 230V AC systems and is not rated for three-phase 400V line-to-line testing. It is not submersible and should be kept clear of wet hands and earthed metalwork during a test. The instrument does not measure insulation resistance, loop impedance or continuity, which need separate functions.
Verified Sparky Direct customer reviews: Kyoritsu 5406A Digital RCD ELCB Tester (5406A)
"Well priced and quick delivery" — Peter
"The unit works well and I would purchase again." — Steve
"the product does what it says it will do" — Simon
(5406A)
The 5406A is built to IEC 61557-1, IEC 61557-6 and IEC 61010-1 CAT III 300V for installation testing. It measures the trip time and trip current of residual current devices, which is the check electricians record during RCD verification.
The 5406A tests Standard (General) and Selective time-delayed RCDs, plus Type AC and DC-sensitive Type A devices. Rated tripping current settings cover 10, 20, 30, 200, 300 and 500mA, suiting most domestic and commercial residual current devices.
The auto ramp test raises the test current from 20 percent up to 110 percent of the rated tripping current. It reports the actual current at which the RCD trips, which helps confirm the device is within characteristic and not tripping early from leakage.
The 5406A uses no battery. It draws power from the 230V circuit under test, so there is nothing to charge or replace before a job. A shoulder strap and cord case are supplied to keep both hands free during testing.
The 5406A ships with a moulded-plug socket lead (Model 7125) for outlet testing. For testing directly at the distribution board or lighting circuits, the optional Kyoritsu 7121B distribution board lead works with the same instrument.
The Kyoritsu 5406A carries a one-year warranty for both domestic and commercial use, starting from the invoice date. Claims are handled on a return-to-Sparky-Direct basis. Keep your proof of purchase, as it is needed for any warranty claim.
The 5406A is a single-phase 230V AC RCD tester and is not rated for three-phase 400V line-to-line testing. It does not measure insulation resistance, loop impedance or continuity; those checks need a separate multifunction or insulation tester.
The Kyoritsu 5406A is available online from Sparky Direct, with Australia-wide delivery to any state or territory including regional areas. Sparky Direct is an Australian electrical wholesaler established in 2005, supplying more than 500,000 customers with transparent trade pricing.
