The Siemens SENTRON 3VA2163-7MN32-0DL0 is a 3-pole molded case circuit breaker (MCCB) in the motor protection variant, rated for 63 A continuous current and carrying a 330 kA interrupting rating at 240 V. It is a current-production part, actively manufactured.
Breaking capacity and trip unit
The interrupting rating drops as system voltage rises: 242 kA at 415 V and 440 V, 187 kA at 500 V, and 52.5 kA at 690 V. The ETU350M electronic trip unit handles the overcurrent protection. It includes phase failure detection, a useful feature for motor circuits where a lost phase can cause single-phasing damage.
Thermal derating and auxiliary contacts
Above that, derating applies: 60.48 A at 55 °C, 59.22 A at 60 °C, 57.96 A at 65 °C, and 56.7 A at 70 °C. The integrated auxiliary trip is a separate orderable subassembly, order code 3VA9608-0BB25. The basic switch itself is order code 3VA2163-7MN32-0AA0.
Physical footprint and environmental limits
Maximum power dissipation is 75 W.
