Vacuum Auxiliary Switch

Auxiliary switches Construction Mani make auxiliary switches have silver û plated fixed contacts, made out of brass, held in molded malamine switch plates. The silver-plated moving contacts, made out of phosphor bronze, are molded on nylon û coated central shaft. Any desired contact configuration, from 2no / 2 nc up to 30 no / nc, is possible in one stack. Make-before-break (mbb) contacts can also be provided when required. Any combination of both the types of contacts to suit specific requirement can be offered. Till today, we have supplied more than a lakh of auxiliary switches successfully to various customers in india, including export to malaysia. Optional features Built in snap-action mechanism is offered as an optional extra. Suitable mounting plates as per requirement are also offered as an optional extra. Shaft extensions to suit specific requirements can be provided.

WSD-VZF(R) -27/630-25 removable vacuum load switch + fuse combination electrical appliances (hereinafter referred to as combination electrical appliances) is a new generation of three-phase AC 50Hz, rated voltage 27kV indoor switchgear developed according to unique design concept and market demand. It is widely used in indoor armoured air insulated switchgear. It meets the requirements of GB3804-2004, GB16926-1997 and other standards. Under normal operating conditions, as long as the technical parameters of the vacuum switch are within the range, it can ensure the safe and reliable operation of the corresponding voltage level of the power grid. Environmental Conditions for Use The ambient temperature should not be higher than + 40, not lower than 10 (storage and transportation allowed at 30) Elevation does not exceed 1500m.
