Product details

It is a three-pole device rated for distribution applications per EN/IEC 60947-2. The H breaking capacity code delivers 100 kA Icu at 220/240 V AC, 70 kA at 380/415 V, and 65 kA at 440 V — figures that cover most industrial service-entrance and distribution panel fault levels. At 480 V AC the UL rating is 65 kA Icu; at 600 V AC it holds 10 kA.

Width 105 mm, height 161 mm, depth 86 mm — fits standard ComPacT NSX panel cutouts. Connection pitch is 35 mm. IP40 enclosure protection; IK07 impact resistance per IEC 62262. Relative humidity range 0 to 95 %.

Durability and electrical ratings

Mechanical durability is 50,000 cycles. Electrical durability at 440 V In is 30,000 cycles; at 440 V In/2 it is 50,000 cycles. At 690 V In it is 10,000 cycles; at 690 V In/2 it is 20,000 cycles. Power dissipation per pole is 5.47 W.
