The Schneider Electric A9N1P25BIN is a 25 A rated, 1-pole miniature circuit-breaker from the Acti9 xC60 range, built to IS/IEC 60947-2. The 25 A [In] rated current sets the continuous load it can carry without tripping — sized for branch circuits feeding lighting, socket outlets, or small motor loads up to that ampacity. Breaking capacity is 10 kA Icu at 220...240 V AC 50/60 Hz, which means the breaker can safely interrupt a fault current up to 10,000 A at that voltage without welding its contacts or failing catastrophically. At 12...48 V DC it rises to 15 kA Icu, and at 60 V DC it drops to 6 kA Icu — important if this breaker is used in a DC control circuit or battery-backed bus. That 18 mm per pole is the standard modular width for a 1P MCB, so it fits existing Acti9 or third-party distribution boards without crowding.
