Description
Switch of loading VNPZ-M1-10/630-20z The autogas triple-pole switch of loading like VNPZR-M1-10/630-20z with the simple built-in spring drive, hand-operated operations of inclusion and shutdown (one movement of a hand) is intended for repeated kommutation under loading of chains of rated three-phase current with a frequency of 50 - 60 Hz and rated current 630 A in networks with the grounded and isolated neutral, is used in cases of the complete distributing devices (CDD), in chambers stationary unilateral service (KSO), in complete transformer substations (KTP).

Execution in accordance with GOST 15150: usual - U2; export - U2; tropical - T3
