What this 3VA2163-5HL36-0HL0 brings to a panel
The Siemens SENTRON 3VA2163-5HL36-0HL0 is a 3-pole molded case circuit breaker rated for 63 A continuous current at 40 °C, with an ETU320 electronic overcurrent release and a built-in shunt trip (STL). It is set up for line protection — no ground-fault monitoring, no undervoltage release, no communication module. The auxiliary contact block ships as 2 auxiliary switches plus 1 trip alarm switch plus 1 electrical alarm switch (HQ configuration). That gives the panel builder a full set of status signals without adding a separate auxiliary module.
Thermal derating and physical fit
The breaker holds its full 63 A rating up to 50 °C ambient. Above that it derates linearly: 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. The operating range spans -25 °C to 70 °C; storage range is -40 °C to 80 °C. Dimensions are 105 mm wide, 181 mm high, 86 mm deep.
