The Siemens 3VA2163-6JQ32-0AA0 is a SENTRON 3VA2 molded case circuit breaker in the line protection version, rated for 63 A continuous current across the full ambient range from 40 °C to 70 °C without derating — that means the 63 A figure holds in a warm panel, not just at 40 °C. Its ETU560 electronic trip unit supports adjustable short-time delay (tr 0.5 to 25 s, tsd up to 0.5 s) and ground-fault monitoring via summation current formation on the L-conductor, which suits it for feeder protection where coordination with downstream breakers matters. Breaking capacity reaches 242 kA at 240 V AC, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 3.8 kA at 690 V — the steep drop above 500 V means this breaker is sized for 240–500 V distribution, not 690 V main incomer duty. The 3-pole frame (105 mm wide, 181 mm tall, 86 mm deep) fits standard SENTRON 3VA2 panel cutouts and busbar arrangements.
The 105 mm width matches the standard SENTRON 3VA2 mounting footprint — direct replacement for earlier 3VA2 frames without busbar rework. Communication function is present (likely via the ETU's integrated communication module or a plug-in accessory), enabling remote trip indication and power monitoring on a fieldbus network.
