The adjustable thermal-magnetic trip unit covers 600 A minimum to 3000 A maximum, so you set the pickup to match the motor full-load current and coordination study. Maximum power loss is 46 W, which matters for enclosure thermal budgeting in a tight MCC lineup. Interrupting capacity varies sharply by system voltage: 330 kA at 240 V, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 5.2 kA at 690 V.
Width 105 mm, height 181 mm, depth 86 mm. That 105 mm width is the standard 4-module MCCB footprint for this frame size — it occupies the same panel cutout as other 3VA2 frame breakers, so a panel laid out for a 3VA2 200 A frame accepts this unit without re-drilling.
Configuration and auxiliaries
If you need shunt trip or remote status beyond the alarm contact, you add the release externally; the basic switch variant under this order code is 3VA2220-7MS32-0AA0.
