The Schneider Electric C60HC163 is a 1-pole C60H miniature circuit breaker from the Multi9 range, rated 63 A with a C-curve thermal-magnetic trip characteristic. It protects a single pole in distribution applications, interrupting faults up to 30 kA Icu at 130 V AC (EN/IEC 60947-2), 15 kA at 230–240 V AC, 20 kA at 60 V DC, and 4 kA at 400–415 V AC.
At 230–240 V AC the rating drops to 15 kA, and at 400–415 V AC to 4 kA. The 20 kA at 60 V DC (1P) covers DC control circuits. These ratings conform to EN/IEC 60947-2, which certifies the breaker for industrial panel use where SCCR headroom matters. For a 63 A single-pole breaker on a 230 V distribution board, the 15 kA Icu is the figure that governs selectivity coordination with the upstream device.
Snap-on DIN-rail mount for standard 35 mm rail in distribution panels or enclosure sub-boards. Single-pole form factor leaves room for adjacent breakers in a multi-pole assembly. The thermal-magnetic trip unit is non-interchangeable — the 63 A rating is fixed at the factory.
