It carries an ETU850 electronic trip unit, configurable for line protection duty, and delivers a short-circuit breaking capacity of 330 kA at 240 V and 242 kA at 415 V. The 3-pole frame is sized at 105 mm wide by 181 mm tall by 86 mm deep, with IP40 protection on the front face for panel-mount applications. That simplifies panel thermal budgeting: no derating curve to apply for a 50 °C or 60 °C enclosure interior. The 330 kA at 240 V and 242 kA at 415 V place this MCCB in the high-interrupting category for 3VA2 frames; at 690 V the capacity drops to 3.7 kA, which still covers most industrial secondary-side faults. ## Integration notes — panel and communication The 105 mm width fits standard 3-pole MCCB panel cutouts in the SENTRON 3VA2 family. The breaker includes a communication function (: Yes), which means it can interface with a bus system for remote monitoring and trip indication — no separate voltage trigger or undervoltage release on this variant. The IP40 front rating is typical for enclosed distribution panels; no washdown protection, so keep it behind a gland plate or enclosure door in wet environments.","metaTitle":"Siemens 3VA2140-7KP36-0AA0 SENTRON MCCB, 40 A, 3-Pole, ETU85","metaDescription":"Siemens 3VA2140-7KP36-0AA0 SENTRON molded case circuit breaker, 40 A continuous, 3-pole, ETU850 electronic trip unit. 330 kA at 240 V.
