recently we have project that compete with EATON DILM40. 

the customer mentioned that EATON's making capacity is much higher than our product. I couldn't find any proof that our product is equal to EATON. 

https://docs.rs-online.com/7793/0900766b81619c54.pdf -→ this is Eaton's data sheet. 

showed Making capacity (p.f. to IEC/EN 60947) upto 690V 560A. 

I don't think that our product can't stand for such environment, but I can't find any proof from our portal. 

Please help~
