Three poles, designed specifically for line protection (cable/feeder protection, not motor branch). Breaking capacity is the headline number that determines where this breaker lives in the distribution hierarchy: 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3 kA at 690 V. That means it can report status and alarm conditions to a PLC or BMS over the SENTRON bus system — useful for remote trip indication and selective coordination in a monitored distribution panel.
How this compares to the 3VA1110 sibling
The 3VA1110-5EE36-0AA0 is a lower-frame 3VA breaker with a 100 A frame and lower interrupting capacity. The 3VA2063-5KQ36-0AA0 sits on a 250 A frame (the '2063' in the order code) with the higher 63 A trip unit and the 187 kA breaking class. Physically, the 3VA2063 is wider (105 mm vs 70 mm for the 3VA1110) and taller — it will not drop into a panel cutout designed for the 3VA1110 without modifying the mounting plate or DIN-rail position. The communication and ground-fault monitoring features are similar across the family.
