3.5 Battery Circuit Breaker Boxes
A battery circuit breaker box houses the battery circuit breaker and
its controller board and is used to connect the battery to the UPS in
installations where the batteries are not contained in the standard
battery cabinet. It is most likely used with 60–125 kVA UPS models.
Several boxes of various current ratings are available and are
similar in their design and content. These are listed below :
100 Amp C.B. # 0120206014 for use with 25 – 40 kva models.
160 Amp C.B. # 0120206014 for use with 50 – 60 kva models.
250 Amp C.B. # 0120206014 for use with 80 kva models.
400 Amp C.B. # 0120206014 for use with 90 – 125 kva models.
