Product details

It carries a rated current of 20 A at 40 °C, derating to 19 A at 60 °C and above — the full thermal curve is flat to 55 °C, then drops one amp per 5 °C step. Breaking capacity hits 75.6 kA at 240 V AC, 52.5 kA at 415 V, and 32 kA at 440 V, with a floor of 7.5 kA at 500 V and 690 V. The auxiliary switch design is two HQ switches. This is a current-production part.

If your panel runs hotter — say 60 °C inside the enclosure — you must derate to 19 A. At 415 V (common in European industrial panels) it still handles 52.5 kA.

Panel integration

Dimensions are 130 mm height, 76.2 mm width, 70 mm depth — a standard 3-pole MCCB footprint for DIN-rail or screw-mount panel installation. The auxiliary switches (two HQ) are built in, so no separate add-on module needed for status feedback.

Frequently asked questions

Where can I buy 3VA1020-3ED36-0AC0 and how do I get a price?

This part is sourced to order against an RFQ through independent distribution. Submit a request for quote (RFQ) for current availability and pricing.

When sourcing 3VA1020-3ED36-0AC0, what's the closest functional second-source — 3VA1020-3ED36-0AA0?

The 3VA1020-3ED36-0AA0 is the base variant of the same basic switch (3VA10203ED360AA0), sharing identical dimensions, pole count, and TM210 release. The -0AC0 adds the two HQ auxiliary switches; the -0AA0 lacks them. Panel fit and wiring are identical — the difference is only the auxiliary contact configuration.

Will 3VA1020-3ED36-0AC0 drop into a panel that was specified around 3VA1020-3ED36-0AA0 without rewiring?

Yes — both variants share the same 130 x 76.2 x 70 mm footprint, same 3-pole layout, and same TM210 release. The -0AC0 simply adds two HQ auxiliary switches. No rewiring needed for the main power circuit; the auxiliary terminals are additional.
