Product details

It is a 3-pole unit rated 63 A continuously at 40 °C, with a thermal derating curve that holds 63 A through 50 °C and drops to 58 A at 70 °C — useful when the breaker sits in a warm enclosure near other heat sources. The auxiliary switches provide status feedback (open/closed) to a PLC or indication lamp.

The breaker measures 76.2 mm wide (3 in), 130 mm tall (5.12 in), and 70 mm deep (2.76 in). The 3-pole width matches standard MCCB panel cutouts and bus-bar spacing for 3-phase systems. The 70 mm depth includes the handle and auxiliary switch housing — verify clearance to the enclosure door or dead-front cover.

Frequently asked questions

What is the breaking capacity of 3VA1163-5EF32-0CC0 at 240 V?

187 kA at 240 V AC, which covers most service-entrance and high-fault sub-distribution applications. At 415 V it is 121 kA, and at 690 V it is 17 kA.

Does this MCCB include an undervoltage release?

Yes, it ships with an undervoltage release (UVR) factory-installed, plus two auxiliary switches (HQ configuration) for status feedback.
