It carries an ETU340 electronic overcurrent release, which gives you adjustable thermal-magnetic curves and a more precise trip than a fixed thermal unit. The 3-pole design fits standard panel footprints at 105 mm wide, 181 mm tall, and 86 mm deep. The interrupting rating is the headline here: 440 kA at 240 V AC, 330 kA at 415 V and 440 V, 220 kA at 500 V, and still 52.5 kA at 690 V. The 52.5 kA at 690 V also means it can serve 690 V industrial loads without needing a current-limiting upstream device. Operating temperature range is -25 °C to 70 °C, storage from -40 °C to 80 °C. The 1.2 W maximum power loss is low enough that ventilation spacing is standard; no forced cooling needed in a typical enclosure. An optional motor drive is available as a field-addable accessory.","metaTitle":"Siemens 3VA2140-8HK36-0AA0 SENTRON MCCB, 40 A, 3-Pole, ETU34","metaDescription":"Siemens 3VA2140-8HK36-0AA0 SENTRON molded case circuit breaker, 40 A rated, 3-pole, ETU340 release, breaking capacity 440 kA at 240 V.
