The N breaking capacity code (50 kA at 415 V AC) places this breaker in the middle of the NSX family — above the B-rated (25 kA) and below the S-rated (70 kA) and L-rated (150 kA) siblings. For a 16 A feeder on a 415 V bus with a 50 kA prospective fault level, this breaker holds selectivity with upstream 630 A or 1000 A frames without needing a higher-rated NSX variant. The 10 kA Icu at 690 V AC covers 690 V line-to-line applications, though the 36 kA at 500 V AC is the more typical industrial figure for 480 V systems.
The 140 mm width and 161 mm height fit standard ComPacT cutouts; the 86 mm depth leaves room for rear-access wiring.
