The Schneider Electric C16B6TM080C is a ComPacT NSX160B moulded-case circuit breaker with a 4-pole configuration and a TM-D thermal-magnetic trip unit rated at 80 A at 50 °C. It carries a breaking capacity of 25 kA Icu at 415 V AC, 50/60 Hz, conforming to EN/IEC 60947-2 — that is the rating that governs its fit in most industrial distribution panels.
The C16B6TM080C's interrupting ratings step down across voltage: 40 kA Icu at 240 V AC, 25 kA at 415 V AC, 20 kA at 440 V AC, and 15 kA at 500 V AC. For a 415 V panel, the 25 kA Icu is the number to coordinate with upstream and downstream devices. The utilisation category A means it is not intended for frequent switching under load — it is a distribution breaker, not a motor-starting contactor. Mechanical durability is 40,000 cycles; electrical durability at rated current (440 V In) is 20,000 cycles, and at half rated current it doubles to 40,000 cycles.
Mounts on a backplate in horizontal or vertical orientation. Front-connected on both the line and load sides. IP40 finger protection on the front face; IK07 impact resistance per IEC 62262. The neutral is on the left and is configurable for no protection (3D) — check your system grounding before specifying.
