Product details

Siemens SENTRON 3VA2040-5KP46-0AA0 — 40 A MCCB with ETU850 Trip Unit

Breaking capacity is rated at 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.

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.
