It carries a continuous current Iu of 63 A at 40 °C, derating slightly at higher ambient temperatures — still 63 A at 50 °C, then 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. That thermal curve means you can load it to full 63 A in most ventilated enclosures without worry. Breaking capacity is voltage-dependent: 52.5 kA at 240 V, 32 kA at 415 V, 13.6 kA at 440 V, and 7.5 kA at 690 V. That 32 kA at 415 V is the figure most European industrial panels care about — it tells you the breaker can safely interrupt a fault up to that level without upstream coordination issues. The overcurrent release is a TM210 thermal-magnetic type — fixed thermal and magnetic trip settings, no electronic adjustment. That keeps it simple and reliable for standard feeder protection. An undervoltage release (UVR) is built in, so the breaker trips if control voltage drops below a threshold — common for emergency-stop or safety isolation circuits. ## Panel fit and integration This 4-pole MCCB measures 130 mm high, 101.6 mm wide, and 70 mm deep — a standard footprint for SENTRON 3VA frame sizes. It mounts on a DIN rail or directly to a backplate; the IP40 front protection means it's suited for enclosed distribution boards where the front face is behind a door or cover. Two auxiliary switches (HQ type) are integrated, providing status feedback for remote monitoring or PLC inputs. No communication module or ground-fault monitoring on this variant — it's a straightforward line-protection breaker with basic signaling.","metaTitle":"Siemens 3VA1063-2ED42-0DC0 SENTRON MCCB, 63 A, 4-Pole, Line","metaDescription":"Siemens 3VA1063-2ED42-0DC0 SENTRON molded case circuit breaker, 63 A rated at 40°C, 4-pole, breaking capacity 52.5 kA at 240 V.
