The 16 A rating holds flat from 40 °C up to 55 °C — no derating needed in a warm panel — and only drops to 15 A at 60 °C through 70 °C, so it handles standard 16 A branch circuits without head-scratching over ambient temperature. Breaking capacity is the headline: 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at both 500 V and 690 V. At 690 V the 17 kA still covers typical industrial motor branch circuits.
Dimensions are 130 mm high, 76.2 mm wide, 70 mm deep — a compact 3-pole footprint that fits standard Siemens SENTRON mounting bases and busbar systems. Power loss is 10.6 W maximum, so in a sealed panel with multiple breakers ganged together, factor that into the thermal budget.
