63 A, 3-pole, B-curve — panel protection for distribution boards
The Schneider Electric A9N3P63BGN is an Acti9 xC60 miniature circuit breaker rated 63 A, 3 poles, with a B tripping curve (magnetic release at 3 to 5 times In). Breaking capacity is 10 kA Icn at both 240 V and 415 V AC, 50/60 Hz, certified to IS/IEC 60898-1. That 10 kA rating at the higher voltage means it handles typical fault levels on a 415 V three-phase supply without needing an upstream current-limiting device in most installations.
Occupies 6 x 9 mm pitches (54 mm width) on the DIN rail, with a depth of 77.5 mm and height of 85 mm. The clip-on mount lets you snap it onto the rail without tools — useful when populating a multi-way board quickly. The toggle actuator gives clear ON/OFF indication, and the contact position indicator confirms the state at a glance — no guesswork during panel commissioning or troubleshooting.
Compliant with IS/IEC 60898-1 for miniature circuit breakers. Overvoltage category IV — suitable for installation at the origin of the installation, before any step-down transformer or long branch circuit.
