The Schneider Electric A9P55632 is an Acti9 iC40H miniature circuit breaker (MCB) — a 1P+N thermal-magnetic unit rated at 32 A with a C-curve trip characteristic. The 32 A rating suits general-purpose socket circuits, lighting banks, or small appliance feeds in commercial and residential panels. Breaking capacity is 10,000 A Icn at 230 V AC, 50/60 Hz — enough for most domestic and light commercial installations where the prospective fault current stays under that level. The limitation class is 3 per EN/IEC 60898-1, meaning it lets through limited energy during a fault, which helps with downstream coordination.
The MCB clips onto a DIN rail. It occupies 2 modules of 9 mm pitch (18 mm total width), with the neutral on the left. Height is 85 mm, depth 74 mm. IP20 rated on the front, IP40 inside the modular enclosure — suitable for dry indoor panels. Wire stripping length is 14 mm. The tunnel-type terminals are accessible from top or bottom, making it straightforward to busbar or wire in a panel.
Certified to EN/IEC 60898-1, carrying VDE quality label. Suitability for isolation is marked on the device (contact position indicator shows ON/OFF and trip status). Earth-leakage protection requires a separate residual current block — not integrated. Rated for altitudes up to 2000 m and relative humidity up to 95 % at 55 °C. Electrical durability is 10,000 cycles; mechanical durability 20,000 cycles — typical for a residential-grade MCB.
