Integration notes
The TM240 trip unit allows field adjustment of the thermal overload setting via a rotary dial — no need to swap the entire trip block when load requirements shift. The nut keeper kit is specific to the DC Power OEM variant; verify that the supplied hardware matches your enclosure's busbar or cable lug pattern.
