Bypass isolation transfer switchesThe bypass isolation switch is designed for applications where maintenance, inspectionand testing must be performed while maintaining continuous power to the load. This istypically required in critical life support systems and standby power situations calling forsafe system maintenance with no power disruptions. Eaton offers bypass options in bothcontactor and power frame transfer switches.BYPASS ISOLATION CONTACTORBypass isolation contactortransfer switches4BYPASS ISOLATION POWER FRAMEBypass isolation power frametransfer switches Rated for 100–3000 A up to 600 V UL 1008 Listed with a short-circuit andshort-time ratingRated for 200–5000 A in open-delayed, openin-phase and closed transition configurations Available in open-in-phase, open-delayedor closed transition Front accessible with top and/or bottomentry availableUL 1008 Listed with a short-circuit and short-timerating.
