The microprocessor controlled SEW 6221EL is an ideal unit for testing trip current and trip time on both single and 3 phase RCD's. It was designed to have an extremely easy-to-use functionality, as tests consist of simple push button operation and a rotary dial for choosing the RCD current. Once your test is complete, readings will then be displayed on the LCD screen.

An added benefit of using the 6221EL model is that it contains an in-built 3 phase rotation indicator.
