Current lifecycle stage per Siemens — this is still a live catalog number, not a last-time-buy or NRND part. That means factory support, firmware updates on the ETU850 if applicable, and no panic to stockpile. No derating curve to chase — the breaker holds 40 A from a cold panel to a hot summer day. That's a very high interrupting rating for a 40 A frame — it's sized for high-fault industrial services, not just branch panels. Communication function means it can talk to a BMS or power monitoring system for load shedding or selective coordination. Power loss is just 1.2 W max — negligible heat in a dense panel.","metaTitle":"Siemens 3VA2140-0KP32-0AA0 SENTRON MCCB, 40 A, 3-Pole, ETU85","metaDescription":"Siemens 3VA2140-0KP32-0AA0 SENTRON MCCB, 40 A continuous, 3-pole, ETU850 electronic trip, 440 kA at 415 V.
