The breaking capacity numbers tell the real story: 220 kA at 240 V, 154 kA at 415 V, 121 kA at 440 V, and still 17 kA at 690 V. That's enough fault-interrupting muscle for most industrial distribution boards without cascading upstream — the 415 V figure alone covers the common European low-voltage network fault levels. Thermal derating is flat from 40 °C to 50 °C — still 50 A — then drops 1 A per 5 °C step to 45 A at 70 °C. If your panel ambient runs 55 °C, you're good for 48 A continuous; at 65 °C, 46 A. That's a predictable curve for a sealed enclosure with no forced cooling. The shunt trip (STL) is included as the auxiliary release design. No ground-fault monitoring module on this order code — if you need GF protection, that's a different variant or an external add-on.

Frequently asked questions
Where can I buy 3VA1150-6EF36-0KH0 and how do I get a price?
This part is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — submit an RFQ for a firm price and lead time.
Will 3VA1150-6EF36-0KH0 drop into a panel that was specified around 3VA1110-5EE32-0JA0 without rewiring?
The 76.2 mm width matches the standard 3-pole SENTRON frame, so the mounting footprint is the same. The depth and height are also identical to the 3VA1110 series. Terminal positions and bus-bar spacing are consistent across the 3VA family — no re-drilling or re-bussing needed for a swap.
What compliance documentation does this brand provide for 3VA1150-6EF36-0KH0?
Siemens SENTRON MCCBs carry IEC 60947-2 certification as standard. The product reference code per DIN EN 81346-2 is Q. For specific RoHS, REACH, and UL documentation, the manufacturer provides declarations on request.
