The Siemens SENTRON 3VA1063-2ED42-0AH0 is a 4-pole molded case circuit breaker rated for 63 A continuous current (Iu) with a TM210 thermal-magnetic release. It's a line-protection device — no undervoltage release, no ground-fault monitoring, no communication module. The interrupting ratings climb to 52.5 kA at 240 V and 32 kA at 415 V, so it handles high-fault panels where a standard MCB would weld shut. The front face carries IP40 protection; the body dimensions (130 mm height, 101.6 mm width, 70 mm depth) fit standard SENTRON mounting footprints.
Interrupting capacity and thermal derating
The 52.5 kA at 240 V and 32 kA at 415 V are the maximum short-circuit currents this breaker can safely clear — useful for main-feed or high-fault subpanels where the available fault current exceeds 25 kA. At 690 V the rating drops to 7.5 kA, so verify the line-to-line voltage before specifying. The TM210 release holds 63 A straight through 50 °C ambient; above that it derates: 60.48 A at 55 °C, 59.22 A at 60 °C, 57.96 A at 65 °C, and 56.7 A at 70 °C. If the panel runs hot, size the load side accordingly.
Auxiliary contacts and enclosure fit
This version ships with 2 auxiliary switches plus 1 trip alarm switch (HQ type) built in — no separate add-on block needed for status feedback to a PLC or annunciator. The latching endurance is rated at 15 000 operations, which is standard for a panel-main MCCB on a feeder circuit. The 101.6 mm width (4-pole) and 70 mm depth mean it fits alongside other SENTRON breakers on the same DIN-rail or mounting plate without odd spacing.
