RCD Testers

KEW 5410

KEW 5410
• 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.
