text: <s>[INST] PF40 protection device I have an existing Sq. D bucket with breaker that I want to feed a new PF40 drive. Is there anyway to use the existing breaker, if sized correctly? Or will my best option be to feed a J class fuseholder from the existing breaker? Thanks in Advance. Rick Miell [/INST] The PF40 can be installed with either input fuses or an input circuit breaker. Refer to User Manual pages 1-8 and 1-9 and Appendix A for details. Hope this helps… - fuzzy logic \\n </s>
