The 10 kA Icn breaking capacity at both 240 V and 415 V AC (50/60 Hz) meets the IS/IEC 60898-1 standard for residential and light commercial distribution boards, so it safely clears a fault up to that level without welding the contacts or cascading upstream. Thermal-magnetic trip technology gives it the dual response: a bimetal strip for overload protection (time-delayed) and a solenoid for short-circuit protection (instantaneous above the magnetic threshold). The 4-pole configuration (4P) switches all phases and the neutral simultaneously, which is standard for three-phase distribution where you want the neutral isolated when the breaker is off. At 72 mm wide (8 x 9 mm pitches) and 85 mm tall, it occupies four modular spaces in a distribution board. Depth is 77.5 mm, which fits most consumer units and sub-distribution enclosures; verify the gland plate depth if the enclosure is shallow. Wire stripping length is 13 mm for both top and bottom connections. Overvoltage category IV means it's rated for installation at the origin of the installation (utility side of the main distribution board), not just downstream sub-circuits. IP20 finger-safe on the front; the busbar area is live when the breaker is on, so the enclosure door should be lockable or tool-accessible. Electrical and mechanical durability are both rated at 20,000 cycles, which is standard for a distribution MCB; expect the mechanical life to exceed the electrical if it's used mainly as a disconnect rather than a daily switch.","metaTitle":"Schneider Electric A9N4P20DGN Acti9 xC60 MCB, 20A D Curve 4P","metaDescription":"Schneider Electric A9N4P20DGN Acti9 xC60 miniature circuit breaker, 20 A rated current, D curve, 4 poles, 10 kA breaking capacity at 240/415 V AC.

That's the maximum fault current it can safely interrupt at those voltages."},{"question":"What does the D curve mean for this breaker?","answer":"The D curve has a magnetic tripping threshold of 10 to 14 times the rated current (In). For the 20 A version, that means instantaneous trip between 200 A and 280 A — designed for loads with high inrush current like motors, transformers, and discharge lighting."},{"question":"What is the closest alternative to A9N4P20DGN in the same family?","answer":"Within the Acti9 xC60 range, the closest alternative would be a different current rating or curve code (e.g., a 20 A C curve or a 25 A D curve) — same 4-pole footprint, same breaking capacity, same DIN-rail mounting. The pinout and terminal layout are identical across the xC60 family."},{"question":"How do I get current pricing and availability for A9N4P20DGN?","answer":"Submit an RFQ through this listing.
