It combines overcurrent protection (thermal-magnetic trip, curve B) with remote switching capability in a single 3-pole unit rated 63 A. The 20 kA Icu at 230...240 V AC (10 kA at 380...415 V) per EN/IEC 60947-2 tells you it can handle substantial fault currents on a 230/400 V distribution network without upstream coordination headaches — the N breaking capacity code means it's the standard-duty version for this frame. This is not a plain MCB. The 'integrated control' function means it accepts remote control by pulse, toggle ON/OFF button, or continuous command (230 V AC, 24 V AC, 48 V AC, 24 V DC, or 48 V DC control voltages).
Fixed mounting mode, so no plug-in base to source separately. Padlockable in the OFF position (provision for padlocking), with a mechanical durability of 50,000 cycles and electrical durability of 50,000 cycles at AC-1. That's a solid 50 k-cycle life for resistive load switching — if you're cycling it daily under load, the electrical endurance number is the one that governs replacement intervals.
Earth-leakage protection is handled by a separate block (not integrated), so if your design requires RCD functionality, you'll need to add an external Vigi iC60 module downstream. The local signalling — red LED for fault, flashing LED for tripped/ready/overheat, green LED for ON — gives a quick visual on status without opening the panel door.
