Eaton’s vacuum interruption technology is used for repetitive switching, motor inrush
current interruption, fault protection, and overcurrent and short-circuit protection. Eaton‘s
environmentally friendly medium voltage interrupters are capable of reliably switching
high-stress currents robustly and carrying their rated continuous current without forced cooling.
