Panel-builder commissioning notes
The A9N3P16BGN is a 3-pole 16 A miniature circuit breaker from the Acti9 xC60 range, curve B (magnetic trip 3...5 x In), rated for distribution duty on 35 mm DIN rail. Breaking capacity is 10 kA Icn at both 240 V and 415 V AC, 50/60 Hz, per IS/IEC 60898-1 — enough to handle typical residential and light commercial fault levels. Thermal-magnetic trip unit, toggle control, ON/OFF indication.
DIN space and integration
The 54 mm width (6 x 9 mm pitches) and 85 mm height fit standard distribution boards and sub-panels. Depth of 77.5 mm leaves clearance for wiring and cover. Pollution degree 3, overvoltage category IV — suited for main distribution panels. IP20 finger-safe front.
