Medium-Voltage Circuit Breaker Automatic Transfer Switches


Redesigned Medium-Voltage (5-15 kv) Circuit Breaker-Type Automatic Transfer Switches and Bypass/Isolation Switches now have 20-50% smaller footprints than before. UL tested, listed, and labeled under UL 1008A and suitable for use in legally required alternate power systems, these switches transfer electrical loads between preferred and alternate power sources through the carefully controlled opening and closing of circuit breakers. Switches can be configured for open- or closed-transition transfer, and though designed for unattended operation, they include controls for manually-initiated operation. All switch functions are controlled by Russelectric’s powerful and versatile RPTCS programmable microprocessor-based control system. These switches also meet or exceed stringent IEEE, NEMA, and ANSI standards.
