Three poles, electronic ETU320 overcurrent release, and a line-protection design make it a straight choice for feeder and distribution panels where you need coordinated short-circuit protection. Breaking capacity climbs to 121 kA at 240 V, drops to 75.6 kA at 415 V and 440 V, then to 52.5 kA at 500 V. IP40 on the front face. The ETU320 trip unit is an electronic, non-communicating overcurrent release.","metaTitle":"Siemens 3VA2063-4HL32-0AA0 SENTRON MCCB, 63 A, 3-Pole, ETU32","metaDescription":"Siemens 3VA2063-4HL32-0AA0 SENTRON molded case circuit breaker, 63 A rated, 3-pole, ETU320 trip unit.
