Medium-voltage transfer, bypass/isolation switches
Russelectric's medium-voltage bypass/isolation switches meet or exceed IEEE, NEMA, and ANSI standards and provide the functions of an automatic transfer switch.
Russelectric’s medium-voltage (5 to 15 kV) circuit breaker-type transfer switches and bypass/isolation switches are tested, listed, and labeled under UL 1008A, making them suitable for use in legally required emergency power systems. These switches transfer electrical loads between normal and emergency power sources through the carefully controlled opening and closing of circuit breakers and may be configured for open- or closed-transition transfer. All switch functions are controlled by Russelectric’s RPTCS programmable microprocessor-based control system. All medium-voltage circuit breaker-type transfer switches meet or exceed stringent IEEE, NEMA, and ANSI standards. They provide all the functions of an automatic transfer switch plus the ability to bypass power from live source to load in the event the transfer switch becomes disabled. In addition, they are designed to allow isolation and de-energization of the automatic transfer breakers for maintenance, testing, and repair.
