Fusible Branch Circuit Panelboards
The Quik-Spec™ Coordination Panelboard (QSCP) simplifies selective
coordination in a fully fused system by using published fuse ampacity
ratio tables. This eliminates lengthy and costly studies required with
circuit breakers. The large 1-600A branch disconnect fuse range
enables closely matching fuse ampacity with UPS loads. Fault current
events do not require the disconnect to be tested and recalibrated as is
the Code requirement for circuit breakers.
To enhance safety, the QSCP branch disconnects utilize a rejection
feature that helps avoid overfusing.
The QSCP offers all these advantages while having a footprint up to 40%
smaller than other fusible panels.
