In a panel where the upstream transformer or main breaker can deliver that fault current, this MCCB holds the line without cascading — the downstream breakers can be lower-rated because this one clears the big faults. At 415 V the 121 kA rating still covers most industrial distribution scenarios. The TM240 overcurrent release is a thermal-magnetic type, so it provides both overload protection (thermal) and short-circuit protection (magnetic) in one unit — no separate relay needed. Dimensions are 130 mm height, 76.2 mm width, 70 mm depth — a 3-pole MCCB frame that fits standard Siemens SENTRON mounting bases and busbar systems. That covers most indoor industrial panel conditions, including unheated warehouses and enclosures near process heat. Maximum power loss is 19.8 W at rated load. That's the heat the breaker dumps into the enclosure — relevant for calculating internal temperature rise in a sealed panel. At 63 A continuous, 19.8 W is moderate for a 3-pole MCCB; no forced cooling required in a properly sized cabinet.","metaTitle":"SENTRON 3VA1163-5EF32-0DA0 MCCB, 63 A, 3-Pole, 187 kA at 240","metaDescription":"SENTRON 3VA1163-5EF32-0DA0 molded case circuit breaker, 63 A rated at 40 °C, 3-pole, 187 kA breaking capacity at 240 V.
