All Siemens circuit breaker with thermal-magnetic trip units may be applied on 400Hz systems, up to 480V, following the de-rating table in the Siemens 2004 SPEEDFAXTM on page 6-100. The interrupting rating will be 5kA or 10% of the 60Hz rating, whichever is greater. Siemens circuit breakers with electronic trip units have not been tested for 400Hz applications.
