Physical dimensions are 86 mm depth, 140 mm width, and 181 mm height. Power loss is rated at a maximum of 2.2 W, which is negligible for thermal dissipation calculations inside a sealed panel — no forced ventilation is required for this single device. ## Environmental and Operational Limits Operating temperature limits are -25 °C to 70 °C. These ratings confirm suitability for installation in unconditioned electrical rooms or outdoor-rated enclosures within those ambient limits.","metaTitle":"Siemens 3VA2040-5KP46-0AA0 SENTRON MCCB, 40 A, 4-Pole, ETU85","metaDescription":"Siemens SENTRON 3VA2040-5KP46-0AA0 molded case circuit breaker, 40 A continuous, 4-pole, ETU850 electronic trip unit.
