Product details

The SENTRON 3VA2063-5JQ32-0CH0 is a 3-pole molded case circuit breaker (MCCB) rated for line protection, carrying a full-scale current of 63 A across the entire ambient range from 40 °C to 70 °C — no derating needed up to that ceiling. Interrupting capacity hits 187 kA at 240 V, drops to 121 kA at 415 V and 440 V, then 75.6 kA at 500 V, and still holds 3 kA at 690 V.

Built-in extras that save panel space

That means you don't need to carve out extra DIN rail for add-on modules — the UVR handles safety-related dropouts, and the auxiliary contacts feed status back to the PLC or annunciator without a separate interposing relay. Communication function is onboard, so it can talk to a higher-level system for metering or remote trip indication.

Depth of 86 mm keeps the back-of-panel clearance manageable, even with wiring gutters.

Frequently asked questions

How do I get current pricing and availability for 3VA2063-5JQ32-0CH0?

Submit an RFQ through the storefront; the part is sourced and quoted to order, with availability and current pricing confirmed at quote time.

What is 3VA2063-5JQ32-0CH0's interrupting capacity at 240 V?

187 kA at 240 V, dropping to 121 kA at 415 V / 440 V, 75.6 kA at 500 V, and 3 kA at 690 V.

What is the closest functional second-source for 3VA2063-5JQ32-0CH0?

The 3VA2063-8JQ32-0AA0 is a close peer — same frame, same 63 A rating, same 3-pole configuration. The main difference is the auxiliary switch configuration and the absence of the undervoltage release on the -8AA0 variant. It will drop into the same panel footprint without rewiring.
