DEVICE FOR PROTECTION OF ELECTRICAL EQUIPMENT Russian patent published in 2017 - IPC H01H85/00 

FIELD: electricity.

SUBSTANCE: unit for protection electrical equipment device comprises two electrodes, an array of carbon-based polymer with a positive temperature coefficient. To increase the capacity of electrical current of the electrodes the plates are made, between which the matrix of the carbon-based polymer to form a multilayer structure. To increase the heat dissipation electrodes are made with fins. Fixing electrical conductors to the device is performed with the help of tips to protect electrical equipment.

EFFECT: increase the current range of its use.
