Product details

The Siemens SENTRON 3VA2063-5JQ32-0AB0 is a 3-pole molded case circuit breaker (MCCB) rated for line protection, with a full-scale current of 63 A across the entire operating temperature range from 40 °C to 70 °C — no derating needed as the panel warms up. Breaking capacity is the headline: 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3 kA at 690 V. The adjustable thermal-magnetic trip range spans 95 A minimum to 756 A maximum, so this breaker can be tuned to protect a feeder or a large motor branch — not a fixed 63 A only.

Integration — footprint and wiring

Communication function is built in, so it can talk to a higher-level system without an add-on module. Power loss is 5.4 W maximum — low enough that ventilation in a typical IP54 steel enclosure is not required, but worth checking if you pack six of these side-by-side.

Frequently asked questions

What is the breaking capacity of this MCCB at 240 V?

187 kA at 240 V, which is very high for a 63 A frame — it handles utility-grade fault levels without needing a current-limiting fuse upstream.

How do I get pricing and availability for 3VA2063-5JQ32-0AB0?

Submit an RFQ through this listing. The part is sourced through independent distribution; current pricing and lead time are confirmed at quote time.

Will 3VA2063-5JQ32-0AB0 drop into a panel built for 3VA2063-8JQ32-0AA0?

Both are 3-pole SENTRON MCCBs in the same 63 A frame, so the footprint — 181 mm high, 105 mm wide, 86 mm deep — is identical. The difference is in the trip unit and auxiliary configuration; check that the 2 auxiliary switches HP match your control wiring before swapping.
