Overview
The A9F73363 is a Schneider Acti9 iC60 miniature circuit breaker rated 63 A with a B-curve trip characteristic, switching three poles in a single 54 mm wide module.
Compared to the A9F79263, the A9F73363 uses 3 poles instead of 2 and occupies 6 module pitches (9 mm each) rather than 4. The B-curve trips at 4 x In ±20 %, while the A9F79263 uses a C-curve at 8 x In ±20 %. Choose the A9F73363 when the BOM calls for 3-pole protection with a lower magnetic threshold for resistive or lighting loads.
