The adjustable trip range spans 60 A to 480 A via the ETU320 — the 40 A frame can be set to protect conductors sized for higher current, but the continuous rating of the breaker itself is 40 A, so the trip setting must stay at or below the conductor ampacity. Dimensions are 105 mm wide (4.13 in) by 181 mm tall (7.13 in) by 86 mm deep (3.39 in). The ETU320 electronic trip unit provides LSI protection — long-time, short-time, and instantaneous. Adjustable short-time delay enables selective coordination. Rated insulation voltage is 800 V, so this breaker is suitable for 480/277 V and 600/347 V systems with margin.","metaTitle":"Siemens 3VA2040-4HL32-0AA0 SENTRON MCCB, 40 A, 3-Pole, ETU32","metaDescription":"Siemens 3VA2040-4HL32-0AA0 SENTRON molded case circuit breaker. 40 A rated, 3-pole, ETU320 release.
