The Schneider Electric A9N2P20CGN is a 2-pole miniature circuit breaker from the Acti9 xC60 range, rated 20 A with a C-curve trip characteristic. The C-curve means the magnetic trip operates between 5 and 10 times the rated current — so for a 20 A breaker, instantaneous trip occurs between 100 A and 200 A. That makes it a good fit for general-purpose loads like lighting, socket outlets, and small appliances where inrush is moderate. Breaking capacity is 10 kA Icn at both 240 V and 415 V AC, certified to IS/IEC 60898-1.
Depth is 77.5 mm, height 85 mm — standard footprint for a 2P MCB in the Acti9 family, so it swaps into an existing board without re-drilling the backplate. The bottom terminals also support a biconnect feature for daisy-chaining or looping out to the next device.
The A9N2P20CGN is listed as current-production (active lifecycle stage). No end-of-life notice or last-time-buy date is available for this order code.
Certified to IS/IEC 60898-1, the Indian-standard version of the IEC 60898-1 for AC miniature circuit breakers. Pollution degree 3, overvoltage category IV — suitable for main distribution boards where the breaker sees the full utility fault level. Tropicalisation level 2 per IEC 60068-1 means it withstands damp heat — relevant for coastal or high-humidity installations. Relative humidity rating is 95 % at 55 °C. Electrical and mechanical durability both rated at 20,000 cycles — typical for a distribution MCB; not a switching device for frequent motor starts.
