380V 3Ph 50 Hz OCPD

[jsl]

Is there any reason that a typical North American thermal magnetic breaker (eg SQ. D FAL) could "not be used" as overcurrent protection for a 380 V 3ph 50 Hz load. The breaker here would be a 480V 3 ph breaker with required current rating. The 50 Hz is my concern, will it affect the coil of the magnetic portion in the breaker?


This is for use as HVAC OCPD , equipment is being installed in China, and the end user wants to follow NEC where possible/practical.

I am looking at a Cutler Hammer BAB 3 pole breaker, no where is a frequency listed on nameplate.

Thanks

the catalog page says 50/60 hz (page 11-20)

It would be an issue for the local authority's requirements on what they require on the nameplate, if any, but in practical terms - especially if it is dual listed in the catalog - it should provide proper protection. I would feel better if the interrupting and withstand rating are also listed for the voltage.
