Explosion-proof switching modules (circuit breakers, switch disconnectors, cam switches) are designed for controlling and protecting electrical circuits against overloads and short circuits, as well as for switching, protective disconnection, and circuit selection. They are used in the chemical, petrochemical, pharmaceutical, and other industries where explosion-proof equipment is required.
