What this 630 A MCCB does for your line
The 110 mm depth and 138 mm width fit standard SENTRON panel cutouts; the 248 mm height clears most enclosure gland plates without a riser.
At 50 °C it's 570 A; at 60 °C it's 510 A; at 70 °C it's 450 A.
Interrupting capacity by voltage — where it matters
At 240 V the breaker clears 187 kA symmetrical. At 500 V it drops to 75.6 kA, and at 690 V it's 9 kA. The steep fall-off above 500 V means this is a 480 V class MCCB — don't spec it for a 690 V motor circuit unless the available fault current is under 9 kA. The minimum breaking capacity is 945 A, so it's not for low-fault branch circuits where a miniature breaker would do.
The 3-pole design with no undervoltage release means you need an external shunt trip if remote tripping is required. Four HQ auxiliary switches are built in, so you get status feedback without an add-on module. No trip indicator and no voltage trigger; the electronic trip communicates via the integrated comms function.
