Product details

What this breaker delivers

The 3-pole design (3D protected poles) and toggle control make it a straight swap for any NSX160N frame slot.

At 220/240 V AC this breaker delivers 90 kA Icu; at 380/415 V AC it holds 50 kA Icu; at 660/690 V AC it still manages 10 kA Icu. The UL 60947-4-1 ratings (85 kA at 240 V, 50 kA at 480 V, 10 kA at 600 V) cover North American motor-circuit applications on the same frame.

IP40 front face (IEC 60529) and IK07 impact resistance (IEC 62262) — fine for enclosed distribution boards but not washdown zones. Front connections top and bottom simplify bus-bar routing in a standard panel layout.

Durability and environment

Rated for 40,000 mechanical cycles and up to 40,000 electrical cycles at 440 V In/2 (20,000 at full In). Operates in 0–95 % relative humidity and up to 2000 m altitude without derating (2000–5000 m with derating). Power dissipation 10.78 W per pole, so factor that into panel thermal calculations.
