HRC fuses

I'm in the US, designing a machine bound for China, from a specification created by a European engineering firm.

The spec says, "The fuses shall be high breaking capacity (HRC) type, minimum rated voltage of 500 V, utilisation category G in accordance with IEC 60269-1."

I've looked through my trusty Bussmann catalog and am getting stuck on the utilsation category G. Does anybody know if this is the same as class aM & gG/gL?

Am I missing something in the spec translation to English? Anybody know if Bussman has a fuse that will work?

(edit: typo correction!)

I would suggest that they mean gG as G is not listed as far as i am aware.

Bussman BS and IEC Fuses page 12 of 18

Thanks, I'll check them out.

(Perhaps the spec translator though gG was a typo and fixed it to G...)
