Eaton Bypass Power Module (BPM), 3U, Hardwired Input

The Eaton BPM125HW is a three-rack-unit bypass power module that combines a maintenance bypass switch and a power distribution unit in one enclosure. It lets technicians move a connected UPS to bypass mode in seconds, so scheduled service or replacement can take place without shutting down critical equipment.

Designed for Eaton 9170+, 9155, and 9PXSP UPS systems from 8 to 10 kVA, the module uses a hardwired split-phase input and supports up to 125 amps of current. By integrating bypass and distribution, it reduces wiring runs, shortens installation time, and frees extra rack space that can be used for servers, storage, or network gear.

With a height of 5.1 inches, a width of 17.3 inches, and a depth of 26.5 inches, the BPM125HW fits neatly into any standard 19-inch rack. A metal chassis that is sturdy and finished in black blends with Eaton rack hardware and keeps the cabinet looking organized.

The module works equally well in small to medium data centers, edge computing closets, telecom rooms, or industrial control cabinets where uptime is a priority and maintenance windows are tight. Facility managers gain a straightforward way to isolate the UPS, while maintaining continuous power to mission-critical loads.

A two-year limited warranty from Eaton provides added confidence that the unit will perform reliably over the long haul.
