The Siemens 3VA2163-0MN36-0AA0 is a 3-pole IEC molded case circuit breaker from the 3VA family, sized on a 160 A frame but fitted with a 63 A motor-protection trip unit (ETU350M, LSI curve). That puts it squarely in high-fault-current industrial panels where the available short-circuit current at the main switchboard exceeds 100 kA.
The overload protection (Ir) is adjustable from 25 A to 63 A, and the short-circuit protection (Isd) from 3 to 15 times Ir. Instantaneous pickup (Ii) is fixed at 15× In. For a motor circuit, the LSI curve allows you to set the magnetic pickup above the motor inrush without sacrificing short-circuit protection — typical for pump, fan, or compressor starters where the locked-rotor current is 6–8× FLA.
Compliance documentation
The breaker carries RoHS compliance (since 01-10-19) and a REACH Article 33 duty-to-inform declaration for lead content. The product family is the 3VA Molded Case Circuit Breakers up to 1600 A, IEC — a standard industrial line with IEC 60947-2 certification.
