Product details

Breaking capacity by voltage level

The 3VA2063-7KP46-0AA0: This MCCB delivers 330 kA at 240 V, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 3 kA at 690 V. That 330 kA figure at 240 V covers high-fault utility feeds and transformer secondaries. The steep drop to 3 kA at 690 V is typical for a 63 A frame — it's not a 690 V main breaker.

Panel fit and environment

Dimensions are 86 mm deep, 140 mm wide, 181 mm tall. Front IP40 — sealed against tools and wires over 1 mm, but not washdown. Operating range spans -40 °C to 70 °C; storage stretches to 80 °C. Maximum power loss is 5.4 W. Mounts in a standard distribution panel or MCC bucket; the 4-pole width at 140 mm is wider than a 3-pole unit, so check your busbar and enclosure fill factor before committing the BOM line.

Frequently asked questions

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

330 kA at 240 V. At 415 V and 440 V it's 242 kA, at 500 V it's 187 kA, and at 690 V it drops to 3 kA.

What trip unit does the 3VA2063-7KP46-0AA0 use?

It uses the ETU850 electronic overcurrent release with adjustable long-time delay from 0.5 s to 25 s and N-conductor protection configurable OFF or 40 % to 160 %.

Does the 3VA2063-7KP46-0AA0 need derating at high ambient temperatures?

No. The 63 A rated continuous current holds flat from 40 °C through 70 °C — no derating required across that range.

Where can I buy 3VA2063-7KP46-0AA0 and what is the lead time?

This part is sourced and quoted to order through independent distribution. Availability and current pricing are confirmed at quote time — submit an RFQ for the current lead time and price.
