C&C Power offers Maintenance Bypass Breaker Cabinets (MBBC) available in multiple configurations. The MBBC allows the end user to safely isolate the UPS from utility power and from the critical load to perform regular service and maintenance. All of this is done while still maintaining power to your critical load.

The MBBC circuit breakers are rated at 600 VAC. All 208 VAC systems are braced for 100,000 AIC and all 480 VAC systems are braced for 60,000 AIC. Mechanical lugs are provided for both input and output terminations. Systems are available in 40-1,200 amp configurations with two or three breaker designs at both 208 and 480 VAC. Multiple Kirk Key configurations are also available.
