Etipo NH fuse link ETI Polam NH2/WT-2C 004114507 gG 100A 500V industrial time-delay (mining termination)

Etipo NH fuse link ETI Polam NH2/WT-2C 004114507 gG 100A 500V is a cartridge-style, time-delay (mining termination) fuse designed for industrial overcurrent protection. It is a gG type fuse intended to provide general-purpose protection against overloads and short circuits while allowing short-duration inrush currents that occur during motor starts or transformer energisation. The construction follows NH (knife-blade) cartridge standards for secure installation in switchgear and distribution assemblies.

Advantages

The time-delay characteristic reduces nuisance trips by tolerating temporary inrush currents while still clearing sustained overloads and short circuits reliably. NH cartridge format ensures robust mechanical stability and compatibility with standard NH fuse holders and switchgear. Rated for 100 A and up to 500 V, the fuse supports a wide range of industrial applications where dependable interruption performance and predictable characteristic curves are required.

Suitable for

• Industrial switchgear and distribution panels
• Motor protection where temporary inrush currents occur
• Transformer primary and secondary protection in industrial systems
• Mining termination assemblies and heavy-duty installations

Key specifications

• Type: gG (general-purpose) time-delay fuse
• Rated current: 100 A
• Rated voltage: 500 V
• Format: NH cartridge (knife-blade connection)
• Characteristic: time-delay to withstand inrush currents
• Application category: industrial overcurrent and short-circuit protection

How to use

Install the NH cartridge fuse in a compatible NH fuse holder or switchgear following the equipment manufacturer’s safety instructions and local electrical standards. Ensure the circuit is de-energised before insertion or replacement. Select this 100 A time-delay gG fuse where the expected operating voltage does not exceed 500 V and where temporary current peaks must be tolerated without nuisance tripping. Verify correct seating of the cartridge and secure the fuse holder cover or interlocks before re-energising the circuit.

Usage recommendations

Use for general-purpose protection in industrial panels and mining terminations where reliable clearing of faults is required while allowing for temporary inrush currents. Match fuse ratings and characteristics with system coordination studies and follow all applicable installation and maintenance standards.
