The 3P+N configuration protects three poles plus switched neutral, with the neutral on the left side of the DIN-rail clip-on housing (54 mm wide, 81 mm high, 78 mm deep). The D curve (magnetic trip 10–14 × In) is the key selector: it allows short inrush currents typical of motor-starting or transformer loads without nuisance tripping. At 25 A, this MCB handles sustained loads up to 25 A and will hold through the 250–350 A peak of a motor start before clearing a hard fault. ## Panel integration Tunnel-type terminals accept 0.75–16 mm² rigid or 0.33–10 mm² flexible conductors; tightening torque is 2 N·m. IP20 finger-safe terminals suit enclosed distribution boards. Tropicalisation class 2 per IEC 60068-1 and pollution degree 3 per IEC 60947-1 mean it tolerates humidity up to 95% at 55 °C and conductive dust typical of industrial panels.","metaTitle":"Schneider A9N21609 iDPN N MCB, 25 A, Curve D, 6 kA, 3P+N, Cl","metaDescription":"A9N21609 Schneider iDPN N miniature circuit breaker, 25 A, D curve, 6 kA breaking capacity at 400 V AC, 3P+N, DIN rail clip-on.
