This European Standard specifies requirements for earth-leakage and open-circuit protective devices designed to protect circuits for neon tubes operating from transformers conforming to EN 61050 at voltages exceeding 1 000 V but not exceeding 10 000 V. NOTE 1Requirements for the installation of earth-leakage and open-circuit protective devices are given in EN 50107-1. NOTE 2Requirements for earth-leakage and open-circuit protective devices used with inverters and converters are specified in EN 61347-2-10.
