The Schneider Electric A9P52616 is an Acti9 iC40 miniature circuit-breaker rated 16 A with a C curve, in a 1P+N pole configuration. It carries a 6 kA Icu breaking capacity at 230 V AC per IEC 60947-2 and 4500 A Icn per IEC 60898-1, so it handles both residential and light commercial fault levels within a single DIN-rail footprint.
Breaking capacity and dual standard
Rated 6 kA Icu (ultimate breaking capacity) under IEC 60947-2 and 4500 A Icn under IEC 60898-1. The 4500 A Icn figure applies to residential distribution boards where the standard expects a lower prospective fault current.
C curve and trip characteristics
C curve means magnetic tripping occurs between 5 and 10 times In (80 to 160 A for this 16 A unit) per IEC 60898-1, with a tighter 8 x In ±20 % tolerance per IEC 60947-2. That suits mixed loads with moderate inrush — lighting banks, small motor starters, and general-purpose socket circuits. The thermal-magnetic trip unit provides overload protection via the bimetal element and short-circuit protection via the solenoid.
Physical integration and environment
Clip-on mounting to DIN rail, 18 mm width (2 x 9 mm pitches), 74 mm depth, 85 mm height. The tunnel terminals accept 1 to 16 mm² rigid or 1 to 10 mm² flexible cable, with a 14 mm strip length and 2 N·m tightening torque.
