FUSIBLE SWITCH ASSEMBLY
Fully Integrated Medium Voltage Enclosed Assembly
Pioneer is now making it possible to order a fusible switch that is fully integrated with our medium voltage transformers. These systems provide dependable, secure, cost effective switching and fault protection.
The switch and transformer assembly are used as the primary main switches of unit substations, acting as a primary load break switch while also providing circuit protection (fused models).
