Automatic transfer switch BTPC series

enclosedfor generatorsfor generator sets

BTPC bypass isolation transfer switches combine a drawout automatic transfer switch with isolation mechanism and a manual bypass switch, to provide redundant power transfer and re-transfer capability for critical-need applications requiring a reliable power supply to the load. BTPC switches are available with closed transition for transferring critical loads without interruption. Like conventional transfer switches, BTPC transfer switches are designed for operation and switching of electrical loads between primary power and standby generator sets. The switch monitors both power sources, signals generator set startup, automatically transfers power and returns the load to the primary power source when the utility returns and stabilizes. PowerCommand® control: A fully featured Microprocessor based control with digital display. Controls allow operator to enter settings and make adjustments to software enabled features easily and accurately. Accommodates up to 8 event schedules. Closed transition available: By briefly connecting the two sources (for 100 msec or less), the transfer from the alternate source back to the normal source occurs without Interruption in the power supply to loads. Programmed transition: Open transition timing can be adjusted to completely disconnect the load from both sources for a programmed time period, as recommended by NEMA MG-1 for transfer of inductive loads. Closed door draw out operation: Bypass and total isolation of the automatic transfer switch occurs behind closed doors, to provide arc flash protection for operator. For critical loads: Suitable for use in emergency, legally required and optional Standby applications.
