Breaking capacity is 187 kA at 240 V AC, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3 kA at 690 V — figures that cover most industrial service-entrance and feeder applications. Dimensions are 181 mm height, 105 mm width, and 86 mm depth. ## Overcurrent release and protection characteristics The ETU320 release is an electronic trip unit with an adjustable current range from 60 A to 480 A — note that the breaker's continuous rating is 40 A, so the release's minimum setting of 60 A means the breaker is applied at its rated 40 A continuous, and the release is set above that for short-circuit and ground-fault protection.","metaTitle":"Siemens 3VA2040-5HL32-0AA0 MCCB, 40 A, 3-Pole, ETU320, 187 k","metaDescription":"Siemens SENTRON 3VA2040-5HL32-0AA0 molded case circuit breaker, 40 A continuous, 3-pole, ETU320 release, 187 kA breaking at 240 V.
