For use with Tripp Lite’s SUT20K 3-phase UPS system, the SUT20KMBP maintenance bypass panel (MBP) maintains total continuity of power to connected load circuits when bypass of the UPS is required for regular service and maintenance. This UPS maintenance bypass panel has three 4-pole circuit breakers for Input, Bypass and Output. The breakers have removable handles to allow the panel’s trim cover to be removed for internal access. The short circuit rating is 10 kAIC. Maximum current capacity is 80A. Made of galvanized steel, the service bypass panel has rear mounting holes for installation on a smooth and solid wall (mounting hardware not included).
