Breaking capacity is 242 kA at 240 V, 187 kA at 415 V and 440 V, 121 kA at 500 V, and still 9 kA at 690 V. That's a full complement of signaling contacts for PLC or SCADA feedback without adding separate modules.
The basic switch is order code 3VA2440-6HN32-0AA0; this -0DL0 suffix adds the UVR and auxiliary/alarm switch package. If you're replacing an older 3VA2 frame, confirm the existing accessory wiring matches this contact configuration.
It's a 3-pole, 400 A continuous breaker with 242 kA interrupting at 240 V, 187 kA at 415 V, and 9 kA at 690 V. The 400 A rating holds across the full 40 °C to 70 °C ambient range.
It comes with an undervoltage release, two auxiliary switches, a trip alarm switch, and an electrical alarm switch — all factory-installed.
