Its breaking capacity class N delivers an Icu of 25kA at 415V — enough for most secondary distribution panels in industrial and commercial builds. The 16A rated current (In) with overload protection adjustable from 11A to 16A (Ir) and short-circuit protection set at 10 to 20 times In (Ii) gives you selectivity headroom downstream. The N conductor is protected at 100% of the phase rating, and the nut keeper kit is pre-fitted for the DC Power OEM variant destined for China.
What the ratings mean in practice
The adjustable Ir (11-16A) lets you fine-tune overload protection to match the actual load, not just the nameplate.
Integration notes
The nut keeper kit simplifies busbar or cable lug termination, saving time during panel build. Wire the line side to the top terminals; load side exits the bottom. Verify the TM240 trip curve matches the downstream cable and load before energizing.
