Product Specification

Gang Operated Air Break Switches

Jaipuria Brothers Electricals Pvt. Ltd. manufacture gang operated air break off load, disconnecting switch with triple pole. Each pole consists of galvanized steel base, H.T. insulators as per B.S.S./I.S. non-ferrous knife and spring loaded contacts, arcing horns of adequate section to break magnetizing current of the transformers horizontal G.I. pipe 01 adequate length for phase separation, adequate length of G.I. pipes for operation from ground level and operating handle complete in both OFF and ON position. All ferrous parts are hot dipped galvanized and non ferrous parts are heavily tinned to withstand extreme weather. Manufactured in accordance with I.S.S., this product is suitable for horizontal vertical mounting.
