Product details

What the 85 kA Icu means for your distribution panel

The C10F42D100 is a Schneider Electric ComPacT NSX circuit breaker, rated 100 A at 40 °C with a MicroLogic 2.2 electronic trip unit providing LSI protection. Its breaking capacity is 85 kA Icu at 240 V AC, 36 kA at 415 V AC, and 22 kA at 525 V AC — all per IEC 60947-2. That's a practical detail for commissioning: you don't get nuisance trips on a restart after a brief overload event.

Mounting and integration — backplate, IP40, IK07

The 140 mm width, 161 mm height, and 86 mm depth fit standard ComPacT NSX cutouts; the 35 mm connection pitch matches busbar and cable-lug spacing for panel builders. IK07 impact rating (2 Joules) covers accidental tool drops during maintenance.

Mechanical durability is rated at 50,000 cycles; electrical durability varies by load — 50,000 cycles at 440 V at half rated current (In/2), 30,000 cycles at full In, and 10,000 cycles at 690 V full In. That's typical for a molded-case breaker in distribution duty — not a switching contactor, but fine for infrequent manual isolation or backup protection.

Frequently asked questions

What is C10F42D100's breaking capacity at 415 V?

36 kA Icu at 380/415 V AC 50/60 Hz per IEC 60947-2, which is the F breaking capacity code for this NSX100F frame.

What protection functions does the MicroLogic 2.2 trip unit provide?

The MicroLogic 2.2 provides LSI protection: L for long-time overload, So for short-time short-circuit with fixed delay, and I for instantaneous short-circuit. It's electronic, not thermal-magnetic, so it gives better accuracy and adjustable pickup settings.
