Product details

The adjustable thermal-magnetic trip unit covers 60 A to 480 A, so it can be set to protect a specific downstream load or feeder without swapping the breaker body.

Breaking capacity is 187 kA at 240 V AC, dropping to 121 kA at 415 V and 440 V, then 75.6 kA at 500 V, and 3.7 kA at 690 V.

Communication and monitoring

This MCCB includes a communication function and an other measurement function — meaning it can report status and measured values over a bus, not just trip.

Physical fit

No special adapter plate needed for a typical 3-pole cutout.

Frequently asked questions

How do I get pricing and availability for 3VA2140-5KQ32-0AA0?

Submit an RFQ through this listing. Availability and current pricing are confirmed at quote time through independent distribution channels.

What is the interrupting capacity at 240 V?

187 kA at 240 V AC, which covers high-fault-current applications like transformer secondaries or large bus risers.

What is the continuous current rating and does it derate with temperature?

40 A continuous, and it holds that rating from 40 °C through 70 °C ambient — no derating required across that range.

What compliance documentation is available for this MCCB?

As a Siemens SENTRON product, it carries the usual IEC/UL certifications and CE marking. Specific documentation (RoHS, REACH, UL, IEC) is available on request with the RFQ.
