The thermal derating curve is published: 250 A continuous up to 50 °C ambient, then 238 A at 55 °C, 225 A at 60 °C, 213 A at 65 °C, and 200 A at 70 °C. The maximum power loss of 48 W at rated load should be factored into the enclosure thermal calculation. A communication function is present, and the ground fault monitoring uses summation current formation on the L-conductor. The basic switch is order code 3VA2225-6JQ32-0AA0, and the integrated auxiliary trip is 3VA9688-0BL32.
The 3-pole form factor with the ETU560 electronic trip unit means it draws power for the trip electronics from the line side — no separate control power needed for the trip unit itself, but the shunt trip (STL) requires an external voltage source to operate. The latching endurance is rated at 20,000 operations.
