The Schneider Electric C60H2P4AD is a Multi9 C60 series miniature circuit breaker (MCB) with a D tripping curve, rated 4 A at 40 °C. It protects a single pole plus neutral (1P+N) in AC distribution circuits. Breaking capacity reaches 30 kA Icu at 230-240 V AC, 15 kA at 400-415 V AC, and 10 kA at 440 V AC, all conforming to IEC 60947-2.
Mounts on a 35 mm symmetrical DIN rail (EN 60715), occupying 4 modular pitches of 9 mm each — 36 mm total width. Dimensions: 81 mm height, 36 mm width, 73 mm depth.
Tropicalisation level 2 per IEC 60068-1 means the breaker is treated against humidity and fungal growth — relevant for installations in warm, damp environments. Limitation class 3 per IEC 60947-2 indicates the let-through energy (I²t) is limited, reducing stress on downstream components during a fault.
