Kyoritsu KEW 5410 RCD (ELCB) Tester

• 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
