The interrupting ratings step down with system voltage: 242 kA at 240 V, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 7.5 kA at 690 V. The minimum trip threshold is 375 A, and the maximum setting goes to 3 000 A, giving a wide coordination band for downstream feeders.
The MCCB measures 138 mm wide by 248 mm tall by 110 mm deep — standard footprint for this SENTRON frame size. The auxiliary switch block (2 aux + 1 trip alarm + 1 electrical alarm) and the integrated shunt trip release occupy the accessory slots; no communication module is fitted, so this is a hardwired-only breaker. The undervoltage release is absent on this variant, so the shunt trip is the sole remote-trip path.
