Siemens SENTRON 3VA1163-5EE32-0AD0 — 63 A MCCB for Line Protection
Its TM220 thermal-magnetic release provides fixed overload and short-circuit protection without adjustable trip settings — a straightforward fit for standard feeder circuits where selectivity coordination is already established. Breaking capacity reaches 187 kA at 240 V AC, 121 kA at 415 V, and 75.6 kA at 440 V, with a drop to 17 kA at 500 V and 690 V. The 70 mm depth, 76.2 mm width, and 130 mm height fit standard Siemens SENTRON mounting bases; panel cutouts and bus-bar spacing match the 3VA platform.
Current Derating and Ambient Temperature
