Abstract

A protective relay (16), particularly for a transformer with an on-load tap changer, comprises a first Reed switch (18) and a second Reed switch (20), which are actuable by magnetic means(24) acting thereon. The first Reed switch (18), the second Reed switch (20) and the magnetic means (24) are arranged within a housing (17). At least one third Reed switch (22), which is actuable by the magnetic means (24) and thus by a magnetic field acting on it, is also provided in the housing (17).
