FAQ

What is the difference between gG and gL fuse characteristics?

The 'gG' characteristic is the modern IEC standard for general-purpose fuses, protecting cables and lines against both overload and short-circuit currents. The 'gL' characteristic is an older German (VDE) standard that is functionally identical to gG. They are generally considered interchangeable for most applications.

No, this fuse is specifically rated for 500V AC (alternating current). Using it in a DC (direct current) circuit is not recommended. DC arcs are much more difficult to extinguish than AC arcs, and using an AC-rated fuse in a DC application can lead to failure to interrupt the fault current, posing a significant fire and safety hazard. Always use fuses specifically rated for the DC voltage and current of your application.

The size '00' (also written as NH00) refers to the physical dimensions of the fuse body and its contact blades according to DIN standards. This ensures mechanical compatibility with fuse holders and switch-disconnectors designed for this specific size. Size 00 is one of the smaller standard NH fuse sizes, commonly used for lower to medium current ratings in industrial distribution boards.
