The interrupting capacity reaches 187 kA at 240 V, stepping down to 121 kA at 415 V and 75.6 kA at 440 V, with a floor of 17 kA at 500 V and 690 V. That high-fault rating makes it suitable for installation close to large transformers or in high-available-fault-current industrial distribution. Dimensions are 130 mm height, 101.6 mm width, and 70 mm depth — a 4-pole MCCB that fits standard Siemens SENTRON mounting footprints. No undervoltage release or shunt trip is fitted on this variant; the TM220 release is the only internal trip element.","metaTitle":"Siemens 3VA1140-5EE42-0AA0 SENTRON MCCB, 4P, 40A, 187kA","metaDescription":"Siemens 3VA1140-5EE42-0AA0 SENTRON 4-pole molded case circuit breaker, 40 A rated at 40 °C, TM220 release, 187 kA at 240 V.
