Above that it derates linearly: 60.48 A at 55 °C, 59.22 A at 60 °C, 57.96 A at 65 °C, and 56.7 A at 70 °C. ## Auxiliary and undervoltage release This variant ships with two auxiliary switches plus one trip-alarm switch (HQ configuration). The integrated auxiliary trip module carries order code 3VA9608-0BB11. No communication function or phase-failure detection is fitted. ## Panel fit and protection class Dimensions are 130 mm height, 76.2 mm width, 70 mm depth — a standard 3-pole MCCB footprint for DIN-rail or screw-mount panel integration.","metaTitle":"Siemens 3VA1163-5EF36-0BH0 SENTRON MCCB, 63 A, 187 kA at 240","metaDescription":"Siemens SENTRON 3VA1163-5EF36-0BH0 molded case circuit breaker, 63 A rated, 187 kA interrupting at 240 V.
