What this 3VA2063-5JQ32-0DA0 is
It's the line protection version — meaning it's set up for feeder or main breaker duty, not motor circuit protection.
63 A continuous at 40 °C is the baseline — but this breaker doesn't derate much until above 55 °C, where it steps down to 60.6 A at 55 °C and 53.6 A at 70 °C. That thermal stability matters in a sealed enclosure or a panel near a heat source.
That's a standard MCCB footprint — it'll drop into most 3VA-series panel cutouts or DIN-rail mounting adapters. The 105 mm width means it takes up three pole spaces in a typical distribution panel. The undervoltage release (UVR) is built in, so no separate add-on module to wire. Communication function is on board — check the ETU560 manual for the protocol (likely PROFIBUS or PROFINET via a communication module).
