Breaking capacity — what the voltage columns tell you
This MCCB delivers 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 17 kA at 690 V. At 690 V the 17 kA is still adequate for most industrial motor circuits; the drop-off is typical of a compact MCCB where arc extinction gets harder as voltage climbs.
At 55 °C it steps down to 240 A, at 60 °C to 235 A, and at 70 °C to 225 A. Dimensions are 248 mm high, 138 mm wide, 110 mm deep — the 138 mm width is the 3-pole frame footprint, so it occupies three adjacent 45 mm module positions on a DIN rail or mounting plate.
Auxiliary contacts and trip unit detail
This variant ships with three auxiliary switches HQ — that is a factory-fitted set of changeover contacts for remote status indication (open/closed/tripped). No undervoltage release, no shunt trip, and no communication module are included on this order code — those are added via the integrated auxiliary trip slot (factory-fitted with 3VA9608-0BB24).
