Rated continuous current Iu is 160 A, and it carries an ETU350M electronic trip unit with phase failure detection built in. The 3-pole body breaks up to 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 17 kA at 690 V — so it handles high-fault industrial services without cascading upstream. The base switch is order code 3VA2216-5MN32-0AA0; the auxiliary trip module is 3VA9688-0BL33.
Current derating — what the temperature table tells you
At 55 °C it derates to 153.6 A, at 60 °C to 150.4 A, at 65 °C to 147.2 A, and at 70 °C to 144 A.
No surprises if you're swapping a 3VA2 variant; the bus-bar and lug kits carry over.
