Product details

The 3VA2340-6HN32-0KH0: This breaker delivers 242 kA at 240 VAC and 187 kA at 415 VAC — figures that place it in the high-interrupting-capacity class. At 690 VAC it still holds 7.5 kA, which covers most industrial motor circuits.

Thermal derating — don't ignore it

Above that, the thermal curve drops: 385 A at 55 °C, 370 A at 60 °C, 355 A at 65 °C, 340 A at 70 °C.

Auxiliary configuration and releases

The shunt trip lets a remote PLC or E-stop circuit open the breaker; the alarm switch signals a trip event back to the control system.

Frequently asked questions

Will 3VA2340-6HN32-0KH0 drop into a panel specified around 3VA1110-5EF32-0AM0 without rewiring?

The 3VA2340-6HN32-0KH0 is a higher-current frame (400 A vs the 3VA1110 series which tops out at lower ratings). Physical dimensions differ; verify the backplate cutout and bus-bar spacing before assuming a direct swap.
