Russelectric transfer, bypass/isolation switches now with smaller footprint
By Renée Francoeur
August 17, 2016 – Russelectric says its newly redesigned medium-voltage (5-15kV) circuit breaker automatic transfer switches and bypass/isolation switches now have 20-50% smaller footprints than before.
Tested, listed, and labelled 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 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 RPTCS programmable microprocessor-based control system. The company notes these switches also meet or exceed stringent IEEE, NEMA, and ANSI standards.
