C&C Power offers Free Standing Maintenance Bypass Breaker Cabinets (MBBC) available in multiple configurations. The 90821 UPS Maintenance Bypass allows the end-user to safely isolate the UPS from utility power and from the load while performing regular service and maintenance. At the same time, maintaining power to your critical load is essential in this process.
The 90821 UPS Maintenance Bypass is available in 35k or 65k AIC ratings with amperage from 30A to 400A. The 12-inch compact design minimizes your footprint and allows you versatility in placement. It has two distributions breakers with a three bypass breaker design. A Kirk Key interlock system protects the breakers. In addition, an SKRU (solenoid key release) option is available for added security.
NEW to this product in security features is the Automatic Bypass interface. This touchscreen logic enhances the safety of the critical load while giving remote access to the system.
Each bypass cabinet is welded with heavy-gauge steel construction and has a single locking front door. Available colors include black or beige. It comes fully assembled and tested from the factory. C&C Power warehouses all maintenance bypass options, therefore, making your lead-time the quickest in the industry.
