Function

Advantages

SOCOMEC industrial fuses protect installations and people from overcurrents for any low voltage electrical circuit.

High level performances • High breaking capacity - 120 kA at 400/500 V, 80 kA at 690 V.

• High short-circuit limitation capacity. • Simple and reliable discrimination. • NH (size 000 to 3) type gG fuse links without striker : 250 VDC, 80 kA, L/R 20ms

High reliability • Absolute protection over time guaranteed by the simplicity of manufacture and function (Joule effect).

• No downgrading of fuse characteristics over time.

Improved safetyThe energy released whilst eliminating the fault (fuse blowing) is contained within the cartridge (no degassing).
