The Schneider Electric C60HB416 is a 4-pole miniature circuit breaker from the Multi9 C60H range, rated 16 A with a B tripping curve.
The C60HB416 carries a 10 kA Icn breaking capacity at 230/400 V AC per EN 60898, which is the standard for household and similar installations. Under IEC 60947-2 (industrial), the Icu ratings step up: 10 kA at 440 V AC, 15 kA at 400–415 V AC, 25 kA at 125 V DC (2-pole series), 30 kA at 230–240 V AC, 40 kA at 125 V DC (3-pole), and 50 kA at 250 V DC (4-pole).
The C60HB416 is a DIN-rail mount miniature circuit breaker, 4-pole wide (72 mm at 18 mm per pole). For a field-service swap, the wiring pattern is straightforward — line in at the top, load out at the bottom, with the fourth pole protecting the neutral if the system is wired for 4-pole isolation. The B-curve means it will hold through normal equipment inrush but trip quickly on a hard fault, which simplifies coordination with downstream MCBs in a radial distribution scheme.
