Product details

The Siemens 3VA2163-0KQ36-0AA0 is a 3-pole SENTRON molded case circuit breaker rated for 63 A continuous current across the full ambient range from 40 °C to 70 °C — no derating needed up to that ceiling.

The 181 mm height clears most distribution board covers. Front IP40 protection means it's suited for enclosed panels where splash or tool ingress is minimal — not for washdown zones. The ETU860 trip unit's communication function requires a separate 24 V supply for the electronics; verify that your control transformer or power supply has the headroom.

Frequently asked questions

What is the breaking capacity of this MCCB at 415 V?

Rated 440 kA at 415 V, which covers most industrial transformer-secondary and large motor feeder fault levels without needing upstream current-limiting fuses.

Where can I buy 3VA2163-0KQ36-0AA0 and get current pricing?

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 commercial response.

What compliance documentation does Siemens provide for this part?

As a SENTRON MCCB, it carries IEC 60947-2 certification and is CE-marked for the European market. RoHS and REACH declarations are available from Siemens on request.

Will 3VA2163-0KQ36-0AA0 drop into a panel specified for 3VA2163-8HM32-0AA0?

Both are 3-pole 3VA2 frame breakers with the same 105 mm width and 86 mm depth, so the mechanical footprint is identical. The difference is in the trip unit and accessories — the -0KQ36-0AA0 carries an ETU860 with communication, while the -8HM32-0AA0 uses a different release variant. Verify the trip curve and auxiliary contact configuration before swapping.
