Product details

It handles fault currents up to 121 kA at 240 V, dropping to 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at both 500 V and 690 V.

Thermal derating and release

That means a panel builder running this breaker in a 60 °C enclosure (common near a drive or transformer) should plan for 77 A max continuous load — not the full 80 A. The TM210 release has an adjustable magnetic trip (li) up to 800 A, so you can tune the instantaneous pickup for motor inrush or cable protection without swapping the breaker.

No communication function on this variant, no motor drive, no ground-fault monitoring — it is a straight line-protection MCCB.

Frequently asked questions

What is the interrupting capacity of 3VA1080-4ED46-0AA0 at different voltages?

121 kA at 240 V, 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at both 500 V and 690 V.

Where can I buy 3VA1080-4ED46-0AA0 and how is it quoted?

This part is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.

Will 3VA1080-4ED46-0AA0 drop into a panel specified for 3VA1020-3ED36-0AA0?

Both are 4-pole SENTRON MCCBs in the same 3VA frame family, so the mounting footprint and bus-bar spacing are identical — no rewiring needed for the physical swap. However, the 3VA1080-4ED46-0AA0 is rated 80 A versus the lower current of the 3VA1020 variant, so verify the load and upstream protection coordination before substituting.
