What this MCB does and where it fits
The Schneider Electric C60H3P63AD is a C60H-series miniature circuit breaker from the Multi9 range, rated 63 A at 40 °C with a D tripping curve (magnetic trip threshold 10–14 × In).
Breaking capacity and what it means for your panel
The C60H3P63AD delivers 30 kA Icu at 230–240 V AC and 15 kA Icu at 400–415 V AC, both per IEC 60947-2. For a panel fed by a transformer with a high short-circuit rating, this breaker stays within its interrupting envelope without needing a current-limiting upstream fuse.
Snaps onto 35 mm DIN rail — 6 module pitches (9 mm each) wide, 54 mm total width, 81 mm tall, 73 mm deep. The toggle gives ON/OFF indication, and there's a contact position indicator for isolation verification (suitable for isolation per IEC 60947-2). Earth-leakage protection is handled by a separate block, not integrated.
