From BM fuse- Cooper Bussmann fuses

High Speed fuse

What is the most significant differences of High Speed Fuse constructions and other fuses???

A: High Speed Fuse used silver elements, other fuses often uses copper element. B: High Speed Fuse have stoned sand. The sand in normal is loose. C: High Speed Fuse are more compact relative to their rated voltage and current compared to normal industrial fuses.

Semiconductor Protection Fuse Standard: 1,European-Square body fuse 2,North America- Round 3,British -BS88 4,Ferrule-France

120VAC-1300VAC, 5A-6,000A

Semiconductor Protection Fuses type:

High Power Rectifier Protection DC Protection (Low Power) DC Protection (High Power) Special Designs fuses

750V-6,000V; 16A-10,000A

When we choose High speed fuse, what we need to consider?

Un = Rated Voltage In = Rated Current I²tPre-Arc = Melting I²t or Pre-arcing I²t I²tTotal = Clearing I²t or Total I²t Watt = Power losses Utilisation Class = aR, gR, gS Derating factors (Kx)
