Its TM210 thermal-magnetic release gives fixed thermal pickup and magnetic trip settings, so you set the continuous current once and let the bimetal handle the overload curve. Rated continuous current Iu is 63 A, and it holds that rating all the way up to 50 °C ambient; above that it derates gradually, dropping to 56.7 A at 70 °C. Interrupting capacity is the real selector here: 52.5 kA at 240 V, 32 kA at 415 V, 13.6 kA at 440 V, and 7.5 kA at 690 V.
Panel fit and auxiliary contacts
The 3VA1063-2ED32-0AE0 measures 76.2 mm wide, 130 mm tall, and 70 mm deep — a standard 3-pole MCCB footprint that drops into most SENTRON distribution panels and switchgear assemblies without re-drilling. It ships with 4 HQ (high-performance) auxiliary switches built in, so you get status feedback for remote monitoring or PLC inputs without adding a separate contact block.
MCCBs of this class are the backbone of low-voltage distribution in industrial control panels, motor control centers, and building power distribution. The 63 A rating suits feeder circuits for groups of smaller motor starters, lighting panels, or sub-distribution boards.
