Description

The Metrel A1422 Three-Phase and Welding Equipment Adaptor is compatible with a range of Metrel PAT testers and enables safety testing on three-phase appliances and ARC welding units. There are multiple sockets including CEE three-phase to 16A 5-pin, 32A 5-pin and 16A 3-pin which allows it to perform active polarity testing, differential leakage measurement and three-phase RCD testing on a range of instruments. It will work with a maximum current of 40A.

Various tests such as open-circuit voltage testing, circuit leakage measurement, no-load voltage testing and insulation testing can be carried out on ARC welding units using the Metrel A1422. A durable waterproof case helps protect from water and dust ingress.
