The C&C Power 90840 UPS Maintenance Bypass With Transformer Cabinet is used in conjunction with an Uninterruptable Power Supply (UPS) to maintain total continuity of power to connected load circuits when bypass of the UPS equipment is required for the performance of regular service and maintenance. 

The 90840 Series is provided with a three-phase transformer on the input side of the maintenance bypass. Input transformers are available in both 480D-208Y/120VAC and 600D-208Y/120VAC configurations. 

The maintenance bypass contains three Cutler Hammer circuit breakers that are protected by a Kirk Key interlock system.
