The C16N3MA100 is a fixed-mount ComPacT NSX160N MCCB for motor protection, carrying a magnetic-only (MA) trip unit rated 100 A at 65 °C. No thermal overload element — it trips on short-circuit only, so an external overload relay must be wired in series for the motor. Three poles, 50/60 Hz, category A utilisation.
At 220/240 V it delivers 90 kA Icu; at 440 V it holds 50 kA; at 525 V it still breaks 35 kA, and at 690 V it clears 10 kA. These numbers govern SCCR for the panel label — the 415 V figure is the one most plant engineers need for 400 V distribution.
Mounts flat on a backplate in any orientation (horizontal or vertical). IP40 enclosure, pollution degree 3, overvoltage category III — fits inside a standard IP54 or IP65 panel. Depth 86 mm, width 105 mm, height 161 mm. Front-connected for both line and load.
Rated for 40,000 mechanical cycles and 40,000 electrical cycles at 440 V at rated current (100 A). Isolation-capable per EN/IEC 60947-2 — the breaker provides visible isolation when toggled off. Power dissipation per pole is 3.8 W.
