Appendix A: Current Protection with Dependent Time Delay

This appendix contains the current protection curves with dependent time delay for the UBZ-304 Universal Motor Protection Unit.

These curves show the relationship between current (as a multiple of rated current) and tripping time for the dependent time delay protection mode. The curves are used when the protection parameter “Imax<>T” is set to “Ind” (independent) mode.

For more information on configuring current protection parameters, see the main manual.
