This is a line-protection design, not a motor-protection breaker; it's sized for feeder or main breaker duty in a distribution panel. The 3VA1163-5EF36-0HC0 measures 130 mm high, 76.2 mm wide, and 70 mm deep. The 76.2 mm width (3 inches) is the standard 3-pole MCCB footprint — it will drop into the same panel cutout as other SENTRON 3VA frames of the same pole count without rewiring the bus bars. The shunt trip (STL) is wired separately from the main power path; it requires a control voltage to be applied to trip the breaker remotely. The two HQ auxiliary switches change state with the main contacts. Above that it derates linearly: 62 A at 55 °C, 61 A at 60 °C, 60 A at 65 °C, and 58 A at 70 °C.","metaTitle":"Siemens 3VA1163-5EF36-0HC0 SENTRON MCCB, 63A, 3-Pole, 187kA","metaDescription":"Siemens SENTRON 3VA1163-5EF36-0HC0 molded case circuit breaker, 63A continuous, 3-pole, 187kA interrupting at 240V.
