Product details

The Siemens SENTRON 3VA2063-5KP32-0CA0 is a 3-pole molded case circuit breaker rated 63 A continuous at 40 °C through 70 °C — no derating needed across that band, which simplifies panel schedules in warm enclosures. Its interrupting capacity hits 187 kA at 240 V, 121 kA at 415/440 V, and 75.6 kA at 500 V, so it handles high-fault service-entrance or distribution positions where upstream coordination demands a stiff short-circuit rating. The line-protection design means it's configured for feeder and main breaker duty, not motor-circuit protection — pair it with a separate overload relay for motor starts.

Integration notes: footprint and release

The basic switch assembly is order code 3VA20635KP320AA0, so if you're stocking spares, that's the internal mechanism to keep on the shelf.

The interrupting rating drops as line voltage rises: 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.

Frequently asked questions

Where can I buy 3VA2063-5KP32-0CA0 and how do I get a price?

This part is sourced to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — send your target quantity and required delivery date for a firm commercial response.

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

187 kA at 240 V. At 415 V and 440 V it's 121 kA, at 500 V it's 75.6 kA, and at 690 V it's 3 kA. The insulation voltage is rated 800 V.

Does this breaker include an undervoltage release?

Yes, the 3VA2063-5KP32-0CA0 ships with an integrated undervoltage release (UVR) for trip-on-loss-of-voltage applications.
