Breaking capacity hits 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 10.5 kA at 690 V — so it handles high-fault utility feeds and transformer secondaries without cascading upstream. The 40 A rating holds flat from 40 °C through 50 °C, then derates to 36 A at 70 °C; that thermal curve matters if you're packing this into a warm panel. The auxiliary trip order code is 3VA9688-0BL30.
Sizing into the panel — DIN footprint and derating
If you're replacing a 3VA1110-5EE32-0JA0, check the width — that peer is a 3-pole frame too, so the rail cutout and busbar spacing should carry over, but verify the lug kit and terminal centerline before committing the gland plate.
