The Siemens SENTRON 3VA2163-7MN36-0AH0 is a 3-pole molded case circuit breaker (MCCB) rated for motor protection, carrying a continuous current Iu of 63 A and a breaking capacity of 330 kA at 240 V. The ETU350M electronic trip unit handles phase-failure detection and adjustable overload curves, so it's suited for protecting motor feeders in industrial panels where high fault current is a risk.
Breaking capacity across voltage levels
The interrupting rating drops as voltage climbs: 242 kA at 415 V and 440 V, 187 kA at 500 V, and 52.5 kA at 690 V.
At 55 °C it derates to 60.48 A, at 60 °C to 59.22 A, at 65 °C to 57.96 A, and at 70 °C to 56.7 A.
