The interrupting capacity is 187 kA at 240 V, 121 kA at 415 V, and 75.6 kA at 440 V, which covers high-fault industrial mains and most transformer-secondaries without cascading upstream. The UVR is factory-installed, so no field retrofit required. Power loss is 19.8 W maximum, which matters for thermal management inside a sealed enclosure. ## Panel integration Dimensions are 130 mm height, 76.2 mm width, 70 mm depth — a 3-pole MCCB footprint that fits standard Siemens SENTRON mounting plates and busbar systems.","metaTitle":"Siemens 3VA1163-5EF32-0DH0 SENTRON MCCB, 63 A, 3-Pole, 187 k","metaDescription":"Siemens 3VA1163-5EF32-0DH0 SENTRON molded case circuit breaker. 63 A, 3-pole, 187 kA SCCR at 240 V.
