The Schneider Electric A9N1P25CGN is a 25 A, 1-pole miniature circuit breaker from the Acti9 xC60 range, designed for distribution boards on 35 mm DIN rail. Breaking capacity is 10 kA Icn at 240 V AC, 50/60 Hz, certified to IS/IEC 60898-1. Thermal-magnetic trip technology with a 25 A continuous rating and a C-curve that holds up to 5× In for magnetic release. The thermal bimetal handles sustained overloads; the solenoid clears short-circuits.
DIN-rail fit and panel integration
Width is 18 mm (2 × 9 mm pitches), so it occupies a single module slot in a distribution board. Depth of 77.5 mm and height of 85 mm leave clearance for wiring and cover panels. IP20 finger-safe protection on the front face; the breaker is intended for installation inside an enclosed panel, not exposed to washdown or outdoor conditions. The white housing carries a toggle actuator with ON/OFF position indication and a contact-position indicator for visual confirmation of the state.
