The TM240 overcurrent release is a thermal-magnetic type, fixed at 63 A. Two HQ auxiliary switches ride along for status feedback. The 76.2 mm width (3 inches) is standard for a 3-pole MCCB in this class — it occupies one 3-inch mounting slot in a SENTRON distribution panel or switchboard. Depth of 70 mm leaves room for rear busbar connections without crowding the gland plate. Power loss is 17.3 W maximum — modest for a 63 A breaker, so thermal management inside a sealed enclosure is straightforward.","metaTitle":"Siemens 3VA1163-5EF36-0AC0 SENTRON MCCB, 63 A, 187 kA at 240","metaDescription":"Siemens 3VA1163-5EF36-0AC0 SENTRON molded case circuit breaker, 3-pole, 63 A (40-70 °C), 187 kA at 240 V.
