170M - Square type, size 00, flat contact, 690 Vac, 25 to 400 A
The 170M series square high-speed fuse features a size00 flat-end contact design, a rated voltage of 690Vac, and a current range of 25 to 400A. It is more compact than sizes 1 to 3, making it suitable for semiconductor circuit protection needs in small and medium-sized rectifiers, drivers, and power electronic devices with limited space.
Product Positioning
The 170M square high-speed fuse with flat-ended contacts provides 690Vac protection from 25 to 400A in size 00. Its compact size makes it suitable for space-constrained small and medium-sized semiconductor protection applications.
Core Product Advantages and Features
High-speed circuit breaking characteristics
Designed specifically for semiconductor devices, it can quickly melt before the fault current rises.
Flat contact design
The flush-end contact design facilitates bolt-fixing installation.
Compact size
Size 00 is the smaller square size in the series, suitable for installations with limited space.
Practical current range
Covering A to 400A, suitable for small and medium-sized rectifier and drive circuits.
