The Schneider Electric C60H4P16AC is a 4-pole miniature circuit breaker from the Multi9 C60H series, rated at 16 A with a C-curve trip characteristic (magnetic tripping between 5 and 10 times In). It is a thermal-magnetic MCB designed for distribution applications, providing overcurrent and short-circuit protection in final subcircuits. The 16 A rating at 30 °C sets the continuous current capacity; derate for higher ambient temperatures per the thermal curve.
The C60H4P16AC delivers 10 kA Icn at 230/400 V AC per EN 60898, and under IEC 60947-2 it achieves 15 kA Icu at 400–415 V AC and 30 kA Icu at 230–240 V AC. The service breaking capacity (Ics) is 7.5 kA at 230/400 V AC per EN 60898, meaning after clearing a fault at that level the breaker remains functional. For DC circuits, it handles 25 kA at 125 V DC (2-pole series) and 50 kA at 250 V DC (4-pole series). These figures give the panel designer room for selectivity coordination downstream. A 16 A C-curve breaker with 10 kA Icn at 230/400 V AC will typically coordinate with a larger upstream device rated above that level, provided the let-through energy is managed. The limitation class is 3 per IEC 60947-2, which limits peak let-through current and energy — helpful for protecting downstream components.
The 4-pole body occupies 72 mm width (8 modules of 9 mm pitch), so plan for 8 DIN spaces in the distribution board. Depth is 73 mm, height 81 mm. The toggle switch provides local ON/OFF indication with a contact position indicator. Earth-leakage protection requires a separate block — not integrated.
