ASCO automatic transfer switches are modern, high-speed switching devices designed to transfer electrical loads from a preferred power source to an alternate power source when voltage and/or frequency varies from preset limits, and to retransfer loads when preferred source is restored. ASCO Series 7000 automatic transfer switches utilize simple electrical operators to provide high-speed quick-break, quick-make, preloaded transfers. The operators are connected to the switch mechanism through precision self-aligning, ball joints and heavy-duty linkage rods which prevent misalignment.
ASCO builds all its transfer switches for years of reliable, trouble-free operation with minimum maintenance. In fact, many ASCO switches have been in continuous service for over 40 years. ASCO transfer switch contacts are segmented and have tungsten arcing tips. All contacts are machined from solid copper — not cast, forged, or stamped. All mechanical assemblies, linkages, and connecting rods are purpose-built a nd precision-machined in-house.
