Keep critical equipment powered during planned UPS service with the Vertiv Liebert ITA2 MBC Maintenance Bypass Cabinet (MBC). Designed for compatible Liebert ITA2 15–40 kVA UPS systems, the cabinet provides a power path around the UPS for maintenance or replacement. A maintenance bypass interlock helps support the correct switching sequence during service.
Choose a compact 4U cabinet for a single UPS or a specialized 9U or 12U paralleling cabinet for supported multi-UPS configurations. Selection depends on your system voltage, UPS rating, number of units, and capacity or redundancy requirements. These MBC configurations are backed by a 2-year warranty.
