63 A MCCB with 242 kA interrupting capacity
The Siemens 3VA2163-6HL32-0AD0 is a SENTRON molded case circuit breaker (MCCB) rated for 63 A continuous current, with a breaking capacity of 242 kA at 240 V — that's the headline number, but what matters for panel design is the full voltage curve: 187 kA at 415 V and 440 V, 121 kA at 500 V, and 5 kA at 690 V. Three auxiliary switches (HQ type) are built in, so you get status feedback without adding external contact blocks.
Panel fit and thermal derating
The breaker measures 105 mm wide × 181 mm tall × 86 mm deep — a standard 3-pole MCCB footprint that fits SENTRON 3VA2 mounting bases. Thermal derating is published: full 63 A up to 50 °C ambient, then it tapers to 60.6 A at 55 °C, 58.3 A at 60 °C, 55.9 A at 65 °C, and 53.6 A at 70 °C.
