Product details

Breaking capacity sits at 10 kA Icn at 380–415 V AC, 50/60 Hz, certified to IS/IEC 60947-2.

The C curve trips magnetically at 8 × In ±20 %. Thermal-magnetic trip technology handles overloads and short-circuits. That's enough lug capacity for a 40 A feeder in standard PVC or XLPE cable.

Lifecycle stage is marked current — this is an active, in-production part within the Acti9 family.

The toggle actuator gives local ON/OFF indication. IP20 finger-safe front; the busbar comb and adjacent breakers share the same pitch. Mechanical durability is rated at 20,000 cycles, electrical at 10,000 cycles — well above the service life of a typical distribution board.

Frequently asked questions

What is the breaking capacity of A9N3P40CIN?

10 kA Icn at 380–415 V AC, 50/60 Hz, and 15 kA Icu at 100–125 V DC, both conforming to IS/IEC 60947-2.

What standard does A9N3P40CIN comply with?

It is certified to IS/IEC 60947-2, the Indian-standard version of the international standard for low-voltage circuit breakers.
