FIELD: instrument engineering.
SUBSTANCE: invention relates to a plug connector for use as a disconnector for current transformers. Two types of short-circuiting means (5, 6) are provided in the plug connector. First short-circuiting means (5) serves to remove extra voltage by short-circuiting the electrical contacts in the plug connector. Second short-circuiting means (6) is designed to short-circuit electrical contacts (3, 4) in the plug connector, when the latter is not in contact. Short-circuiting means (5, 6) are configured such that first short-circuiting means (5) serves as a fuse in the event of failure of second short-circuiting means (6).
EFFECT: technical result is prevention of extra voltage in the plug connector.
