Product details

Siemens SENTRON 3VA2063-5KP32-0KA0 — 63 A MCCB with Shunt Trip

The Siemens SENTRON 3VA2063-5KP32-0KA0 is a 3-pole 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. Its interrupting capacity hits 187 kA at 240 VAC, dropping to 121 kA at 415 V and 440 V, then 75.6 kA at 500 V, and 3 kA at 690 V. The built-in shunt trip release (STL) allows remote tripping via a control signal, useful for emergency-stop or interlock circuits in a panel.

At 690 V the IC drops to 3 kA, so this breaker is not intended for 690 V high-fault applications — that's a selection boundary. The shunt trip (STL) release draws power only during the trip event; it does not add continuous coil load to your control transformer.

Frequently asked questions

Where can I buy 3VA2063-5KP32-0KA0 and how do I get a price?

This part is sourced and quoted to order against an RFQ through independent distribution. Submit a request for a firm price and availability confirmation at quote time.

What is 3VA2063-5KP32-0KA0's interrupting capacity at different voltages?

The breaker delivers 187 kA at 240 VAC, 121 kA at 415 V and 440 VAC, 75.6 kA at 500 VAC, and 3 kA at 690 VAC. The 187 kA figure at 240 V covers high-fault secondary-side distribution scenarios.

Does the 3VA2063-5KP32-0KA0 include a shunt trip?

Yes, it is equipped with a shunt trip release (STL) for remote tripping via a control signal, suitable for emergency-stop or interlock circuits.

What are the physical dimensions of this MCCB?

Width is 105 mm, height is 181 mm, and depth is 86 mm. The 105 mm width is standard for a 3-pole MCCB, fitting typical panel cutouts and DIN-rail mounts.
