At 480 V AC it still holds 65 kA Icu (UL 60947-4-1), so it coordinates downstream without cascading into the main. The 4-pole version with neutral on the left (1 x Ir setting) handles three-phase plus neutral distribution cleanly.
Front connections top and bottom make busbar or cable entry straightforward. IP40 front face and IK07 impact resistance suit enclosed panel installation.
This part is sourced to order against an RFQ through independent distribution channels. Availability and current pricing are confirmed at quote time.
Within the ComPacT NSX family, the closest alternative would be a unit with the same frame (NSX100H) but a different trip rating — for example, a 63 A TM-D trip. The frame, dimensions, and mounting are identical; only the trip unit rating changes.
The range is ComPacT, and the product name is ComPacT NSX. The device short name is NSX100H, indicating the 100 A frame size.
The depth is 86 mm, with a width of 140 mm and height of 161 mm.
The breaker is certified to EN/IEC 60947-2 and UL 60947-4-1. The IP degree is IP40 per IEC 60529, and the IK degree is IK07 per IEC 62262. Pollution degree 3 per IEC 60664-1. RoHS/REACH documentation is typically available from the manufacturer for current-production parts.
