FIELD: electrical engineering; power industry.
SUBSTANCE: effect is achieved as the current sensor and the reacting element are designed in the form of an aluminum rack with two prismatic magnetic cores fixed on it; fixed contacts and a rotating spring-loaded armature with movable contacts are located at the end of these magnetic cores, while the current conductor is placed between the magnetic cores.
EFFECT: increased reliability of the overcurrent protection of the conductor from short circuits and expansion of the scope of the device.
