170M - Square type, size 23, flat-end contact, 660 Vac (IEC), 1000 to 4000 A
The 170M square fuse size 23, rated at 660Vac IEC, covers a current range of 1000 to 4000A. Its flat-ended contact design facilitates mounting in busbar systems and is a common specification in Bussmann's high-speed fuse series suitable for high-current protection at general voltage levels.
Product Positioning
Both are size 23 models, but the 660Vac version has a lower voltage but a higher current limit compared to the 1250Vac version, making it suitable for high current protection needs of general AC voltage levels.
Core Product Advantages and Features
High current protection
Current range of 1000 to 4000A, suitable for larger current loops.
IEC standard rating
Rated voltage 660Vac, designed according to IEC 60269-4 standard.
Flat contact design
Easy to directly bolt to the busbar
Wide range of applications
