KYORITSU RCD Tester KEW 5410 is a rugged and waterproof device designed to meet IEC60529 IP54 standards. The backlight feature aids in use under low lighting conditions.
Automatically switches current for circuit breaker measurement
Remote testing with lockable test button allows holding the measuring leads with both hands and automatically starts measurement upon detection of main voltage.
Continuous voltage measurement in each range using standby mode
Automatic contact voltage testing can detect earth leakage current during RCD testing to prevent electric shock due to faulty earth wires. The measurement stops at AC50V or higher.
RCD trip time measurement tests residual currents outside the specified range x ½ and measures trip times in ranges x 1 and x 5.
