The Schneider Electric A9N4P04CGN is a 4-pole miniature circuit breaker from the Acti9 xC60 family, rated 4 A with a C-curve trip characteristic. Rated 4 A continuous at 240 V or 415 V AC, 50/60 Hz, with a breaking capacity of 10 kA Icn at both voltage levels — enough for most residential and light commercial distribution panels in IEC markets.
C-curve and trip behaviour
The C-curve means the magnetic trip fires at 5 to 10 times the rated current (20–40 A for this 4 A unit). That suits circuits with moderate inrush — lighting banks, small motor loads, general socket outlets — where you want to ride through the start-up surge without nuisance tripping but still clear a hard fault fast. Thermal-magnetic trip technology handles the overload curve (bimetal strip) and the short-circuit response (solenoid) in one compact package. Limitation class 3 per IS/IEC 60898-1 means it limits let-through energy well in a fault, reducing stress on downstream equipment.
Occupies 8 x 9 mm pitches (72 mm wide) for the 4-pole body. Depth is 77.5 mm, height 85 mm, so plan for at least 100 mm clearance in front of the rail for the toggle and wiring. IP20 finger-safe front, pollution degree 3 rated — fine for clean indoor panels, not for wet locations.
This is an active catalogue item in the Schneider Acti9 range, widely specified in Indian and IEC markets for distribution boards.
