Rated breaking capacity is 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3 kA at 690 V. At 400/415 V, the 121 kA rating covers most transformer-fed industrial services with high available fault current. ## Thermal derating and ambient range Maximum power loss is 5.4 W, manageable for thermal budgeting in a crowded DIN-rail panel. Dimensions are 181 mm height, 140 mm width, 86 mm depth. The 86 mm depth fits shallow enclosures; the 140 mm width for a 4-pole MCCB is standard. Verify the mounting footprint against the existing backplate or DIN-rail adapter.","metaTitle":"Siemens 3VA2063-5JQ46-0AA0 SENTRON MCCB, 63 A, 4-Pole, 121 k","metaDescription":"Siemens SENTRON 3VA2063-5JQ46-0AA0 molded case circuit breaker, 63 A continuous, 4-pole, 121 kA breaking capacity at 415 V.
