Abstract—Electromagnetic overcurrent releases have become widespread among electromagnetic devices in control systems and electrical energy distribution when protecting against negative effects of short-circuit currents. They should provide a high speed when the electrical circuit us broken in the emergency mode. This can be achieved with a small mass of a moving element and significant values of electromagnetic force. For the purpose of approximate determination of the characteristics, the methods of the theory of circuits are still widely used. By simplifying the structure of the magnetic field model, the conductivity of air gaps between ferromagnetic elements of the magnetic system can be determined with reasonable accuracy using a modified probable magnetic flux path method.
