Frequently Asked Questions

What is the main application of these knife-type fuses?

They are designed for AC systems to provide overload and short-circuit protection for low voltage turnkey solution equipment.

What standards do these products comply with?

All products follow the GB/T 13539.2 and IEC 60269-2 performance standards.

What does the "gG" category mean?

The "gG" category indicates full-range breaking capacity fuses for general applications, protecting against both overloads and short circuits.

How does altitude affect the fuse performance?

For every 100m increase above 2000m, the temperature rise increases by approx 0.5K, while ambient temperature decreases by about 0.5°C. In closed environments, rated current may need reduction.

What are the flame retardant requirements for these fuses?

Combustible materials used in the fuses, including plastics, meet the UL94 V-0 flame retardant grade.

What is the maximum rated voltage available?

The PRB and P series offer protection for high voltage AC systems up to 1140V.
