Dimensions, mounting, and integration
Depth at 86 mm leaves room for rear-connected busbars or cable lugs in a shallow backpan. The base variant is the 3VA2220-7MS32-0AA0; the -0AE0 adds the auxiliary switch block.
That's unusual; many MCCBs start derating above 40 °C. The adjustable trip range (600–3000 A) lets you set the magnetic pickup to match the motor's locked-rotor current without swapping trip units. That covers unheated warehouses and outdoor enclosures in most climates. No communication function, no phase failure detection — this is a straight electromechanical breaker, not a smart metering device.
