摘要

Improvements in thermomagnetic circuit breakers with low-sensitivity and high-sensitivity current protection by means of differential transformer, according to which improvements the protection device is organized on a general dielectric basis on which a thermo-magnetic circuit breaker is installed that receives the conductors of phase and neutral establishing a ground connection before the entrance to the circuit breaker, and also, at the exit from it these conductors are wound on a bull-shaped magnetic deferential extending said conductors constituting in the load outlet, whose coils are balanced in the magnetic field and they do not produce flow in the circuit of form of bull, while there is no leakage to earth.
