双电压开关 50A Dual Voltage Switch

Eaton（Cooper）双电压开关 50A Externally Operated Series Multiple (Dual Voltage) Switch

Eaton connects primary windings with its Cooper Power™ series 50 A externally operated singlephase under-oil series multiple switches used either in series for a higher winding ratio or in parallel for a lower winding ratio.

This versatility allows one transformer to be stocked that can be used at either of two system voltages. This minimizes inventory and eases voltage conversion. Time-consuming manual voltage changeovers inside the transformer tank are also eliminated.

The 50 A switches may be used for 2:1 or lower voltage ratios only. Typical voltage ratios include:

2400 x 4800 7200 x 11430

4160 x 7200 7200 x 13200

4160 x 7620 7200 x 13800

4800 x 7200 7200 x 14400

4800 x 7620 7620 x 13200

4800 x 7970 7620 x 14400

Series multiple switches are designed for use in distribution transformers filled with transformer oil, Envirotemp™ FR3™ Fluid or an approved equivalent. The switch body, rotor and shaft are made of high strength glass-filled thermoplastic material. The operating shaft is sealed against leakage by high temperature resistant Viton® O-rings. Built-in internal stops ensure proper contact positioning between settings.
