170M - Square type, size 1 to 3, flat contact, 1250 Vac (IEC), 1300 Vac (UL), 50 to 1400 A
The 170M series square fuses are Bussmann high-speed semiconductor fuses with sizes 1 to 3 flat-ended contacts, rated at 1250Vac (IEC) and 1300Vac (UL), and current ranging from 50 to 1400A. They provide fast circuit breaking protection for semiconductor components and power electronic circuits, and are suitable for applications such as rectifiers and frequency converters.
Product Positioning
The 170M square high-speed fuse is a dedicated protective fuse designed by Bussmann for semiconductor components. The flat-ended contact type provides a protection range of 1250Vac (IEC)/1300Vac (UL) and 50 to 1400A in sizes 1* to 3, making it suitable for high-voltage rectification and power conversion equipment.
Core Product Advantages and Features
High-speed circuit breaking characteristics
Designed specifically for semiconductor components, it can quickly melt before the fault current rises, protecting expensive power components.
Flat-end contact design
It adopts a flush end contact type, which facilitates direct bolt fixing to the busbar or busbar.
Dual-specification certification
The rated voltage has been verified by IEC 1250Vac and UL 1300Vac respectively, meeting both international and North American standards.
Wide current range
Covering sizes from 50A to 1400A, suitable for various square sizes including size 1*, 1, 2, and 3.
