Russelectric® RTS-30 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-30 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. No other manufacturer offers such a comprehensive range of 30-cycle & 3-cycle-rated bypass/isolation switches. All RTS Series switches come equipped with the new RPTCS — the industry’s most powerful, most versatile microprocessor-based transfer control system.
Russelectric RTS-30 & RTS-03 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. With the bypass/isolation switch above the ATS, Russelectric’s vertical space-saving design reduces the unit’s footprint. Feeder connections are housed in a third compartment accessible through a rear panel or door, and the compartments are separated by barriers to protect personnel. The ATS is on casters so that, once it has been bypassed and isolated, it can be rolled out of the enclosure safely and easily.
RTS-30 & RTS-03 Series Bypass/Isolation Switches are available in versions for open-transition (with Russelectric’s proven break-before-make operation) and closed-transition transfer as well as load-break and no-load-break bypass. In fact, Russelectric is the only manufacturer to offer both load-break and no-load-break bypass switches. Open-transition versions are available with single or dual operators. They are also available with an external manual operator which allows manual operation of the switch with the door fully closed for greater arc flash protection.
