SENTRON 3VA2163-6KP42-0AA0 — 63 A MCCB with ETU850 Release
The Siemens SENTRON 3VA2163-6KP42-0AA0 is a 4-pole molded case circuit breaker rated for a continuous current of 63 A across the full ambient range from 40 °C to 70 °C, with no derating required. The interrupting ratings are class-leading: 242 kA at 240 V, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 3.8 kA at 690 V.
The breaker occupies 140 mm width, 181 mm height, and 86 mm depth — a compact footprint for a 4-pole MCCB with integral electronic trip. Panel cutout and busbar spacing should be verified against the existing layout, but the dimensions align with the SENTRON 3VA2 frame family, so a panel designed for a 3VA2 breaker will accept this unit without rewiring. Front-face protection is IP40, sufficient for enclosed distribution boards. The ETU850 release includes a communication function, enabling integration with energy management or remote monitoring systems via the SENTRON communication bus.
