Product details

ComPacT NSXm 160H — MCCB with integrated earth-leakage

The Schneider Electric C12H44V160B is a ComPacT NSXm 160H moulded-case circuit breaker rated 160 A at 40 °C, 4 poles, with a MicroLogic 4.1 electronic trip unit. The integrated earth-leakage protection — selectable from 30 mA to 5 A, class A or AC — means this single device covers both overcurrent and ground-fault protection, saving a panel row and a separate RCCB.

Overvoltage category IV means it can be installed at the service entrance, not just downstream.

Front connections top and bottom accept compression lugs or busbars. 12-module pitch (9 mm each) means it occupies 108 mm width in a panel; depth is 80 mm, height 144 mm. Neutral is on the left. The 35 mm connection pitch with spreaders (27 mm without) matches standard busbar drilling patterns. Local signalling flag (green) shows presence of auxiliary contacts — useful during commissioning to confirm the aux contact block is seated.

That matters for motor or transformer feeders where repeated inrush can accumulate heat. Electrical durability is 20,000 cycles at rated current and 440 V, halved to 10,000 cycles at In/2 — fine for a panel main or feeder, not for a switching duty contactor.

Frequently asked questions

What is C12H44V160B's interrupting rating?

Performance level H: 70 kA at 415 V AC. That is the high-breaking variant of the NSXm 160 frame, suitable for high-fault-current installations.

What earth-leakage sensitivities does the MicroLogic 4.1 offer?

The integrated earth-leakage protection is selectable: 30 mA, 100 mA, 300 mA, 500 mA, 1 A, 3 A, or 5 A, for both class A and class AC detection. This covers everything from personnel protection (30 mA) to feeder ground-fault alarm (5 A).
