What this MCCB carries and where it fits
The Siemens 3VA1063-2ED32-0HH0 is a 3-pole SENTRON molded case circuit breaker rated for 63 A continuous current at 40 °C, holding that rating flat through 50 °C before a gentle derate begins — 60.48 A at 55 °C, 56.7 A at 70 °C. That thermal curve means it can sit in a warm enclosure without losing headroom on a 60 A feeder. Breaking capacity runs 52.5 kA at 240 V, 32 kA at 415 V, 13.6 kA at 440 V, and 7.5 kA at 690 V, so it handles high-fault industrial panels on 480 V or 600 V class distribution. The TM210 thermal-magnetic release provides fixed thermal and magnetic trip settings — no field adjustment, which simplifies spec-in for a standard feeder or branch circuit. Rated insulation voltage is 800 V, and the front face carries IP40 protection — fine for a panel-mounted breaker behind a closed door, not for washdown zones. The shunt trip release (STL) is integrated, and the auxiliary contact block is configured as two auxiliary switches plus one trip alarm switch (HQ). No undervoltage release, no communication module, no ground-fault monitoring on this variant — it is a straight line-protection breaker for a panel where remote trip signaling and a shunt trip for emergency-off are the only auxiliary functions needed.
What the ratings mean for panel fit
Dimensions are 130 mm height, 76.2 mm width, 70 mm depth — a standard 3VA frame size that drops into the same DIN-rail or screw-mount footprint as other 3VA1 breakers. The 70 mm depth leaves clearance behind a 200 mm deep enclosure for wiring and the shunt trip leads. Latching endurance is rated at 15,000 operations, which covers routine switching in a panel that sees weekly maintenance isolation.
