When current passes through the coil, a magnetic field is generated and magnetic energy is stored; when the current changes, the coil generates an induced electromotive force (Lenz's law), which hinders the change of current ("passes direct current and blocks alternating current" characteristics)
HAIPART coils feature a built-in shielding structure, effectively suppressing interference from grid harmonics and transient voltage fluctuations. They maintain signal transmission accuracy even in complex power environments, reducing the probability of false tripping and extending the overall service life of the circuit breaker.
