Bypass/Isolation Switches Are UL Listed For 30-Cycle Closing

Dec. 22, 2009
New Russelectric RTS Series Bypass/Isolation Switches are available in continuous current ratings from 100 to 3000 amps.

New Russelectric RTS Series Bypass/Isolation Switches are UL labeled and listed for 30-cycle closing and withstand ratings based on testing per UL Standard 1008.  Available in continuous current ratings from 100 to 3000 amps, these switches dramatically simplify the selective coordination of overcurrent devices in backup power systems for healthcare and other mission-critical facilities.

The 30-cycle rating of Russelectric RTS Series Bypass/Isolation Switches allows downstream overcurrent protective devices to clear a fault before upstream devices.  Consequently, they greatly simplify the engineering task of selective coordination mandated by the National Electrical Code for emergency and legally required standby systems. 

Russelectric RTS Series Bypass/Isolation Switches combine an automatic transfer switch with a manual bypass/isolation switch that allows the transfer switch to be isolated for inspection, maintenance, repair, or testing.  The bypass/isolation switch is designed to also function as a manually operated backup transfer switch when the unit’s automatic transfer switch (ATS) is disabled or de-energized.
