The C160H3FM is a basic frame from the Schneider ComPacT NS630b...1600 new generation range — a manually operated, fixed-mount 3-pole frame rated 1600 A at 50 °C. It carries no control unit or protection module, so you add a separate trip unit (e.g., Micrologic) to define the protection curve. The breaking capacity is 85 kA Icu at 240 V AC, 70 kA at 415 V, and 65 kA at 440 V — that is the maximum fault current the frame can safely interrupt at those voltages per IEC 60947-2. The integral instant protection is set at 40 kA, a fixed magnetic threshold that acts as a backup if the trip unit fails. Rated impulse withstand voltage is 8 kV and the short-time withstand current is 19.2 kA for 1 second, which matters for selectivity coordination downstream.
Deployment context
This frame bolts to a backplate in a fixed mounting pattern with a 70 mm connection pitch. It is sized for distribution applications — main switchboard or large sub-distribution — where the 1600 A rating feeds a bus or a high-current load. The IP40 enclosure protection means it is suited for indoor panel installation where no water jets are present; the front face is Class II insulated for operator touch safety. Mechanical durability is 10,000 cycles, electrical durability varies by voltage and current — 1,000 cycles at full rated current at 690 V, up to 5,000 cycles at half current at 440 V. That is a standard-duty frame, not a high-cycle switching device.
