ComPacT NSXm 160H — 160 A MCCB with integrated earth-leakage
The C12H34V160B is a Schneider Electric ComPacT NSXm 160H moulded-case circuit breaker (MCCB) rated 160 A at 40 °C, with a 70 kA interrupting capacity at 415 V AC — the H performance level. It carries a MicroLogic 4.1 electronic trip unit and integrated earth-leakage protection, making it a single-device solution for distribution circuits that need both overcurrent and ground-fault protection in one DIN-rail-mountable package.
The electronic trip unit (MicroLogic 4.1) provides adjustable long-time, short-time, and instantaneous protection curves, plus the integrated earth-leakage function with selectable sensitivity from 30 mA up to 5 A for both class A and class AC detection. That covers everything from personnel protection (30 mA) to equipment ground-fault (5 A) without a separate relay. The IP40 enclosure and IK07 impact rating handle typical panel conditions; not washdown-rated, so keep it inside the enclosure.
It occupies 9 module pitches (9 x 18 mm) on a DIN rail, 108 mm wide. Connection is front-facing for both line and load sides, using compression lugs or busbars. The connection pitch is 35 mm with spreaders, 27 mm without. The grey (RAL 7016) housing is standard for the ComPacT range. A green flag signals presence of auxiliary contacts.
