Siemens 3VA2163-6HL32-0BA0 — 63 A MCCB with Undervoltage Release
The Siemens SENTRON 3VA2163-6HL32-0BA0 is a 3-pole molded case circuit breaker (MCCB) rated for 63 A continuous current at 40 °C, with a line-protection ETU320 trip unit. Its interrupting capacity reaches 242 kA at 240 V AC, 187 kA at 415 V, and 5 kA at 690 V — figures that govern selectivity and SCCR coordination in a distribution panel. No auxiliary contacts or communication module are fitted on this variant.
Above that, derating applies: 60.6375 A at 55 °C, 58.275 A at 60 °C, 55.9125 A at 65 °C, and 53.55 A at 70 °C.
Dimensions: 181 mm height, 105 mm width, 86 mm depth. The 3-pole footprint fits standard Siemens SENTRON mounting bases and busbar systems in distribution panels. The undervoltage release wiring terminates at the integrated trip block.
