Industrial fuses

NFC-DIN industrial fuselinks gG and aM curves from 0.16 to 1250 A

Socomec industrial fuses protect installations and people against overcurrents for any low voltage electrical circuit.

Advantages

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.

High reliability

• Absolute protection over time guaranteed by the simplicity of manufacture and function (Joule effect).
• No downgrading of fuse characteristics over time.

Improved safety

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

Standard and option features

High speed fuses (UR)

gR and aR curves 5 to 2000 A

High speed fuses (UR) protect power semi-conductors and DC circuits.

Advantages

High level performances

• Very high breaking capacity up to 300 kA.
• Very high limitation of short-circuit currents (and therefore significant reduction in the thermal and mechanical stress).
• High resistance to cyclic loads.

High reliability

• Absolute protection over time guaranteed by the simplicity of manufacture and function (Joule effect).
• No downgrading of fuse characteristics over time.

Improved safety

The energy released whilst eliminating the fault (fuse blowing) remains contained within the cartridge (no degassing).

Fuse blown detection

An auxiliary contact can be adapted for fuse blown indication
