- Description
The C164160D1S is a 4-pole Schneider Electric ComPacT NSX160NA DC PV switch-disconnector rated for 160 A (DC-22A) at 1000 V DC. Built on the standard ComPacT NSX body, it isolates photovoltaic strings or DC distribution circuits ahead of protection, without an Icu breaking-capacity rating of its own.

Selection Notes
The C164160D1S's DC-22A rating means it is built to switch 160 A under load repeatedly at 1000 V DC — the duty a PV string isolator sees at every maintenance cycle, unlike a general-purpose DC-20 disconnector meant only for no-load isolation. Its 2.5 kA/1 s short-time withstand covers brief fault current while the upstream DC protection clears it. Step up to the C164200D1S 200 A frame when the array's string current exceeds 160 A.
