The Siemens 3VA2163-6HN32-0AE0 is a 3-pole SENTRON molded case circuit breaker (MCCB) rated 63 A continuously from 40 °C through 50 °C ambient — no derating needed in a standard 40 °C panel. Above that, the ETU350 electronic trip unit follows a controlled derating curve: 60.6375 A at 55 °C, 58.275 A at 60 °C, 55.9125 A at 65 °C, and 53.55 A at 70 °C. For a panel builder sizing a 63 A feeder in a 50 °C enclosure, this breaker delivers full rating without oversizing the frame.
Breaking capacity by voltage
The interrupting rating scales with system voltage: 242 kA at 240 V, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 5 kA at 690 V.
Trip unit and auxiliary configuration
The basic switch assembly code is 3VA2163-6HN32-0AA0.
