FIELD: electrical engineering.
SUBSTANCE: invention relates to the field of electrical engineering and power industry. According to the invention, the measuring transducer and the reacting element are made in the form of an H-shaped rack made of insulating material, on which two ferromagnetic magnetic cores are fixed parallel to each other with holes at one of their ends. The contacts of the reed switch are inserted into these holes so that the air gap of this reed switch is located between these magnetic cores.
EFFECT: increasing the reliability of the operation of the overcurrent protection device.
