The built-in shunt trip (STL) release lets a remote signal (e.g., emergency-stop contact, undervoltage relay) open the breaker electrically, which is the usual reason a buyer specifies this variant over a plain thermal-magnetic unit. That matters for panels packed tight or installed in warm enclosures — the 63 A nameplate applies only if the internal panel temperature stays under 50 °C. The breaker measures 76.2 mm wide by 130 mm tall by 70 mm deep — a standard 3-pole MCCB footprint that drops into most SENTRON or third-party distribution panels without re-drilling.","metaTitle":"Siemens 3VA1163-4EF32-0HA0 SENTRON MCCB, 63 A, 121 kA at 240","metaDescription":"Siemens SENTRON 3VA1163-4EF32-0HA0 molded case circuit breaker, 63 A, 3-pole, 121 kA breaking at 240 V, shunt trip release.
