Pioneer Dry Type Group introduces Medium Voltage Transformer/Interrupter Switch Assemblies which provide safe, reliable and cost-effective switching and fault protection for unit substations. Designing and manufacturing the fully integrated switch and transformer together ensures that the components work together. On-site assembly is simplified since all components are factory-tested as a single unit. Disconnected for delivery, all applicable cables are provided and clearly marked for reconnection. Full load current interrupting capability combined with accurate, calibrated fuse protection makes these designed-together packages ideal for industrial, utility and commercial applications.

Available in 5KV and 15KV class models, for 600A or 1200 Amp Continuous Load interrupting rating, these value-added products enhance the extensive Pioneer product offering.  The new Transformer/Interrupting Switch Assembly provides customers a choice of market leading switch manufacturers, with or without fusing, NEMA 1 or 3R enclosures and switch orientation on the right or left side of the transformer. Custom designs for specific applications available. All Pioneer Medium Voltage Transformer/Interrupting Switch Assemblies meet IEEE, ANSI, UL, and CSA standards/certifications. 

A wide range of options are available, including Kirk Key interlocks, 4-in. infra-red window, current limiting fusing, blown fuse indicator, fuse clips, spare fuse pocket, thermostat, strip heater, surge arrestors, insulated bus, ground ball stud w/cover, indicator lights, and more.
