The Eaton BladeUPS
Maintenance Bypass Module
(MBM) is a fully featured
maintenance bypass designed
to transfer power from a
fully populated 60 kW N+1
BladeUPS system into bypass,
allowing maintenance and
service to be performed on a
de-energized BladeUPS cabinet
without affecting power to the
critical load. Factory installed
225A @208V (150A @400V)
maintenance bypass breaker
(MBB), UPS Input Breaker (UIB)
and UPS output breaker (UOB).
A breaker interlock bar ensures
the proper sequencing of the
MBB and UOB when bringing the
BladeUPS cabinet off and online.
The MBM’s Activate UPS
Bypass Mode switch simplifies
the process of going to bypass
even further by providing a
single point to transfer all
BladeUPS units into bypass, and
ready the system for the transfer
of power.

The MBM is designed to fit
seamlessly into your data center
environment while occupying
minimal space. The 6U housing
features front panels designed
to mimic the look of BladeUPS
EBM extended battery modules
(EBMs) so that it will fit
aesthetically into your BladeUPS
rack. Behind the removable
front panels are four LEDs that
highlight the current power flow
of the system and enhance the
safety and security of on-site
operators.
The MBM also features a shunt
trip on the bypass breaker
for interfacing with remote
emergency power-off (EPO)
systems, and all breakers have
auxillary contacts (NC and
NO available) for breaker on/
off sensing for integration with
building control or monitoring
systems.
