About this product
The Kyoritsu 5410 is an RCD tester used to check residual current devices in electrical installations. It tests RCD trip time at x1/2, x1 and x5 of the rated residual current, measures residual current, and checks voltage and contact voltage. It automatically stops testing when contact voltage exceeds AC 50 V.

Frequently asked questions
What does the Kyoritsu 5410 test?
It tests RCD trip time and residual current, and it checks voltage and contact voltage. The x1/2 scale does not trip the device at rated current, while the x1 and x5 scales are used for trip time testing.
What safety feature does the tester provide during contact voltage checks?
The tester detects contact voltage on the protective earth conductor and automatically stops the test when it exceeds AC 50 V. This is intended to avoid electric shock during testing.
