Autogas load switch VNAP-10/630-20-U2

The VNAP-10/630-20-U2 autogas load switch is designed for on-load switching of three-phase alternating current (AC) circuits with a frequency of 50–60 Hz and a rated voltage of 10 kV. This equipment ensures reliable switching on and off of load currents, as well as the creation of a visible circuit breaker in the off position, ensuring safety during repair and maintenance work on electrical installations. Its operating principle is based on autogas extinguishing of the electric arc that occurs when the contacts open. Under the influence of the high arc temperature, the walls of the arc-extinguishing chamber emit an intense gas flow, which effectively extinguishes the arc at the moment of opening. The breaking capacity is provided by a spring mechanism. The rated current is 630 A, the rated voltage is 10 kV, and the rated breaking current is 20 kA. The drive position is right, without grounding knives or fuses. Climatic version – U2 (moderate climate, for work in closed spaces).
