KEW 5410 RCD 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 the 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 standby 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.
