The A9P42632: The B curve means the magnetic trip operates at 3 to 5 times In (96 to 160 A), making it a fit for resistive and general-purpose loads where inrush is modest — lighting, small heaters, control circuits. The thermal-magnetic trip unit handles overloads on the thermal side and short-circuits magnetically.
Rated breaking capacity is 6 kA Icu at 230 V AC (EN/IEC 60947-2) and 4500 A Icn at 230 V AC (EN/IEC 60898-1). Limitation class 3 (EN/IEC 60898-1) keeps let-through energy low. The IP20 finger-safe terminals and IP40 modular enclosure cover the panel interior; no additional sealing is needed inside a standard IP54 cabinet.
Clip-on mounting to DIN rail, neutral on the left. Tunnel terminals accept 1 to 16 mm² rigid or 1 to 10 mm² flexible wire; strip length 14 mm, tightening torque 2 N·m. The 2-module width (18 mm per pitch) fits standard 9 mm pitch DIN-rail accessories. Rated for 10,000 electrical cycles and 20,000 mechanical cycles — adequate for a distribution panel where the breaker is rarely switched under load. The toggle gives ON/OFF indication plus a separate trip indicator for fault status at a glance.
