The interrupting capacity scales with system voltage: 121 kA at 240 V, 75.6 kA at 415 V and 440 V, 52.5 kA at 500 V, and 3 kA at 690 V. ## Ratings that matter for fit Front face carries IP40 protection — suitable for general indoor panel use where tools or fingers won't contact live parts. Not rated for washdown environments. Dimensions are 181 mm high, 140 mm wide, 86 mm deep — a standard 4-pole MCCB footprint for Siemens SENTRON 3VA2 frames. Verify the mounting hole pattern matches your existing backplate or DIN-rail adapter before ordering.","metaTitle":"Siemens 3VA2063-4HL42-0AA0 SENTRON MCCB, 63 A, 4-Pole, ETU32","metaDescription":"Siemens SENTRON 3VA2063-4HL42-0AA0 molded case circuit breaker, 63 A continuous, 4-pole, ETU320 trip unit.
