The Schneider Electric A9N4P32BGN is a 4-pole miniature circuit breaker from the Acti9 xC60 range, rated 32 A with a B-curve trip characteristic. Not the curve for motor starting or transformer primaries; that's a C or D curve part. Breaking capacity is 10 kA Icn at both 240 V and 415 V AC, 50/60 Hz, certified to IS/IEC 60898-1. That's the standard for household and similar installations — the 10 kA rating covers most utility-side fault levels in commercial and residential distribution boards. Overvoltage category IV and pollution degree 3 confirm it's rated for the mains entry point, not just sub-circuits.
The 4-pole body takes 8 x 9 mm pitches (72 mm wide), 85 mm tall, 77.5 mm deep. IP20 finger-safe front, so it's panel-mount only — no washdown exposure. Thermal-magnetic trip unit, thermal for overload, magnetic for short-circuit. Local ON/OFF indicator on the toggle. Earth-leakage protection requires a separate block — this is the MCB only, not an RCBO.
