The TM240 thermal-magnetic trip unit gives you an adjustable overload (Ir) from 22 A to 32 A and a fixed magnetic short-circuit pickup (Ii) at 5 to 10 times In — so for a 32 A breaker, that's 160 to 320 A instantaneous. That range suits motor branch circuits or feeder protection where you need to ride through inrush without nuisance tripping.
Clamp connection terminals accept copper or aluminum conductors up to the frame's rated cross-section. The factory-fitted auxiliary switch (HP) and trip alarm switch (HP) give you remote status feedback — the auxiliary tracks the breaker's on/off position, the alarm signals a trip event. Both are wired to a terminal block on the breaker face, so you don't need to open the cover to check state.
