SEL-7206 panels provide optimized low-impedance bus differential protection for distribution buses with one main, one tie, and up to five feeders. These panels include the following features:
This module provides subcycle low-impedance bus differential, breaker failure, and backup overcurrent protection for buses with up to five feeders. You can add up to two of these modules per panel to protect two bus segments with up to ten feeders.
This module provides independent mechanical lockout for the bus protection (86B). Available with up to two lockouts.
The Firmware IDs for older versions of the firmware can typically be found in Appendix A of the instruction manual.
