Product details

The breaker includes a communication function for integration into a plant monitoring system, and its 138 mm width and 248 mm height fit standard MCCB mounting footprints in switchboards.

Above that the thermal curve drops: 375 A at 55 °C, 350 A at 60 °C, 325 A at 65 °C, and 300 A at 70 °C. The maximum power loss is 96 W, so enclosure ventilation matters in a sealed cabinet.

Interrupting capacity across voltage levels

The interrupting ratings drop sharply as voltage rises: 242 kA at 240 V, 187 kA at both 415 V and 440 V, 121 kA at 500 V, and 7.5 kA at 690 V.

Auxiliary contacts and basic switch

The basic switch assembly is order code 3VA2340-6KP32-0AA0.

Frequently asked questions

Where can I buy 3VA2340-6KP32-0AH0 and how do I get a price?

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

Will 3VA2340-6KP32-0AH0 drop into a panel specified around 3VA2116-5JP32-0AE0 without rewiring?

No — the 3VA2340 is a larger-frame breaker with different mounting dimensions and busbar spacing. A panel originally laid out for the 3VA2116 would need mechanical and electrical modifications to accept this 400 A unit.
