Breaking capacity runs 75.6 kA at 240 V AC, 52.5 kA at 415 V, and holds 7.5 kA all the way up to 690 V. The TM210 release combines a thermal bimetal for overload protection and a magnetic coil for short-circuit trips — no electronic adjustment, no auxiliary power needed. Set it and forget it; the thermal curve tracks cable heating naturally. ## Thermal derating — the real-world current Full 63 A holds through 50 °C ambient. At 55 °C it drops to 62 A, at 65 °C to 60 A, and at 70 °C to 58 A. That DC rating is worth noting for battery-bank or UPS branch circuits — most MCCBs in this frame size don't carry a 600 V DC mark. Four-pole configuration covers three-phase plus neutral switching. The N-conductor protection design is marked 'Without' — meaning the neutral pole is switched but not protected (no overcurrent trip on the neutral).","metaTitle":"Siemens 3VA1063-3ED42-0AA0 SENTRON MCCB, 63 A, 4-Pole, 75.6","metaDescription":"Siemens SENTRON 3VA1063-3ED42-0AA0 molded case circuit breaker, 63 A at 40 °C, 4-pole, 75.6 kA at 240 V.
