The C60H2P20AD is a 1P+N miniature circuit breaker from the Schneider Electric Multi9 C60H range, rated 20 A at 40 °C with a D tripping curve (10–14 × In magnetic threshold). It delivers 10 kA Icu at 440 V AC and 30 kA Icu at 230–240 V AC per IEC 60947-2, making it suitable for distribution boards where high inrush loads — motor circuits, transformers, lighting banks — need a delayed magnetic trip to avoid nuisance tripping on startup.
The 10 kA Icu at 440 V AC and 30 kA Icu at 230–240 V AC (both per IEC 60947-2) give this breaker solid fault-clearing headroom for most commercial and light industrial panels. The 15 kA rating at 400–415 V AC covers common three-phase distribution voltages. For DC applications, the 25 kA Icu at 125 V DC (2P series connection) handles battery-bank or UPS output protection. The D curve's 10–14 × In magnetic threshold means it tolerates the short-duration current surge of a motor start or a capacitor bank charge without tripping — a common pain point when a C-curve breaker nuisance-trips on the same load.
Snaps onto a 35 mm symmetrical DIN rail (per), occupies 4 modular pitches (36 mm width per), and stands 81 mm tall with a 73 mm depth behind the panel. The left-side neutral position and fixed mounting mean it aligns consistently in a multi-row distribution board — no neutral-bar rework when swapping from a different MCB brand.
Tropicalisation treatment per IEC 60068-1 (2 levels) and limitation class 3 per IEC 60947-2. The breaker is suitable for isolation (yes, per IEC 60947-2) and includes an ON/OFF indication on the toggle. Earth-leakage protection requires a separate block — not integrated.
