Breaking capacity is the headline: 187 kA at 240 V AC, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3.7 kA at 690 V. At 690 V the capacity drops to 3.7 kA, which still covers most industrial motor-circuit faults at that voltage level.
Integration notes
The breaker ships with two auxiliary switches (HQ design) and an undervoltage release fitted. No communication function or ground-fault monitoring is built in — this is a plain line-protection MCCB. If you need remote trip indication or ground-fault sensing, you add external modules or choose a different variant.
