Product details

What this MCCB does on a panel

It carries a 242 kA interrupting capacity at 240 V, dropping to 187 kA at 415 V and 121 kA at 500 V — at 690 V it still holds 3 kA. The breaker includes a communication function and ground-fault monitoring via summation current formation on the L-conductor — that's a built-in residual-current detection that sums the phase currents to find leakage to ground, saving an external RCD module in the panel.

That's unusual for an MCCB; most start pulling current back above 40 °C. Dimensions are 181 mm high, 105 mm wide, 86 mm deep — standard SENTRON 3VA footprint, so it drops into existing 3VA busbar systems and mounting plates without re-drilling.

Frequently asked questions

What is the interrupting capacity of 3VA2040-6KQ36-0AA0 at 240 V?

242 kA at 240 V, dropping to 187 kA at 415 V and 440 V, 121 kA at 500 V, and 3 kA at 690 V.

Where can I buy 3VA2040-6KQ36-0AA0 and get current pricing?

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

Does 3VA2040-6KQ36-0AA0 include ground-fault protection?

Yes, it has ground-fault monitoring via summation current formation on the L-conductor — built-in residual-current detection without an external module.
