Breaking capacity reaches 242 kA at 240 V, dropping to 187 kA at 415 V and 440 V, 121 kA at 500 V, and 3 kA at 690 V. Four-pole construction means it occupies the full width of a standard 140 mm MCCB mounting base — verify the backplate cutout and bus bar spacing if replacing an existing 3-pole unit. Front-side protection is IP40, adequate for enclosed panel mounting where no water ingress is expected. The trip indicator is not fitted on this variant — the ETU320's status is read through the electronic display or remote signaling if wired.","metaTitle":"Siemens SENTRON 3VA2040-6HL42-0AA0 MCCB, 40 A, 4-Pole, ETU32","metaDescription":"Siemens SENTRON 3VA2040-6HL42-0AA0 molded case circuit breaker, 40 A continuous, 4-pole, ETU320 electronic trip unit.
