Breaking capacity is substantial: 220 kA at 240 V, 154 kA at 415 V, 36 kA at 440 V, and 17 kA at 690 V.
Above that it derates: 194 A at 55 °C, 188 A at 60 °C, 182 A at 65 °C, 176 A at 70 °C.
Physical fit and auxiliary contacts
Dimensions are 140 mm wide, 158 mm high, 70 mm deep. That gives you a remote status signal for the breaker's open/closed state and a separate contact that closes only on a trip event, which is useful for alarm annunciation or PLC input without extra wiring. Front protection is IP40 — sealed against tools and small solids, but not washdown.
