Maintenance Bypass Panel (Optional)
Line-up-and-match products are available
from APC Custom Engineering Group as
options. The Symmetra
®
MW Maintenance
Bypass Panel (MBP) is equipped with 100%
rated circuit breakers for reliable UPS
bypass operation. Main features of the MBP
include:
• Input/output fuses, current transformers,
busbars for connection to the UPS, and
termination points for input connections.
• Input/output circuit breakers.
• Output connections to critical load and
connections to load bank.
• Circuit breakers for External Bypass Static
Switch and termination points for bypass
input connections.
• External Bypass Static Switch with built-in
controller.
The withstand current of the MBP is 100 kA. The MBP has its own input/output area, so if your
installation includes an MBP, the Input/Output Section of the UPS system is not required, thus
reducing footprint and cost. An External Bypass Static Switch is incorporated in the MBP. The
MBP is bus-connected to the UPS.
