Russelectric’s medium-voltage (5 to 15 kV) circuit breaker-type transfer switches and bypass/isolation switches are UL 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 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.
Though designed for unattended operation, switches include controls for manual operation and provide maximum protection for personnel. All medium-voltage circuit breaker-type switches meet or exceed stringent IEEE, NEMA, and ANSI standards.
