170M - Square, size 00 to 3, DIN 43620, full range (gR) 690 Vac (IEC), 10 to 800 A
gR full-range square high-speed fuses are designed according to DIN43620 dimensions, with sizes from 00 to 3,690Vac rated and currents ranging from 10 to 800A. They can handle both overload and short-circuit faults, have low energy let-through and excellent heat dissipation, and are suitable for high-power applications such as DC drives, rectifiers and power conversions.
Product Positioning
The 170M gR full-range square high-speed fuse can provide both overload and short-circuit protection simultaneously. Compared with the aR fuse which only provides short-circuit protection, it is more suitable for DC power systems that require full-range protection.
Core Product Advantages and Features
gR full-range protection
It has both overload and short circuit protection capabilities, making it more widely applicable than aR partial range fuses.
High breaking capacity
With a rated breaking capacity of 300kA RMS symmetry value, it can withstand high fault current environments.
Low-energy let-through
It features low arc voltage and low energy release characteristics, which helps protect downstream semiconductor components.
DIN43620 Compatible
It conforms to DIN43620 dimensions and can be interchanged with existing high-speed fuse systems.
