Medium voltage refers to the range from 1 kV to 52 kV (alternating voltage). These voltages are usually used for distribution and industrial power systems.
They include numerous circuit breakers (for up to 120,000 operating cycles) and reclosers, switchgear such as circuit breakers (for IEC and UL markets), switches, switching contactors, busbar section disconnectors, switch disconnectors and ground switches and non-switching equipment, such as fuses, instrument transformers and surge arresters and surge limiters.
