Etipo NH00/WT-00 004111226 gG 40A 500V industrial fuse link (time-delay)

Etipo NH00/WT-00 004111226 gG 40A 500V is an NH00-size industrial fuse link with a gG characteristic and time-delay behaviour. It is rated for 40 amps and 500 volts and is designed for general-purpose protection in distribution boards, control panels and industrial equipment. The time-delay (slow-blow) design allows the fuse to tolerate short inrush currents while providing reliable interruption for sustained overloads and short circuits in low-voltage power distribution systems.

Advantages

This NH00 fuse link combines standardized NH00 sizing with a gG breaking characteristic to protect conductors and equipment against overload and short-circuit conditions. The time-delay feature reduces nuisance blowing during motor starts or transformer inrush, while maintaining fast interruption for faults that exceed the fuse’s interrupting capacity. The construction is suitable for installation in NH fuse holders and mounted fuse blocks commonly used in industrial panels.

Suitable for

• Protection of motor circuits and motor starters where inrush currents occur
• General circuit protection in distribution boards and power distribution systems
• Control panels and switchgear in industrial or commercial installations
• Protection of cables and downstream equipment from overloads and short circuits

Key specifications

• Fuse size: NH00 (compact NH format)
• Rated current: 40 A
• Rated voltage: 500 V
• Characteristic: gG (general-purpose, full-range protection)
• Time-delay behaviour: slow-blow / time-lag for improved inrush tolerance
• Mounting: designed for NH fuse holders and blocks
• Application category: low-voltage industrial distribution and control circuits

How to use

Install the fuse link into a compatible NH00 fuse holder or fuse block with the supply disconnected and observing appropriate safety procedures. Verify that the holder and associated terminals are rated for the fuse’s current and voltage. Select this 40 A gG time-delay fuse where protection against both overload and short-circuit is required and where transient inrush currents (for example from motors or transformers) should not cause nuisance trips. Replace blown fuses only with the same type and rating to preserve protection characteristics.

Usage recommendations

Ensure proper coordination with upstream and downstream protection devices by checking time-current characteristics and system selectivity. Use correct-size fuse holders and ensure secure, low-resistance connections. For installations with frequent thermal cycling or high ambient temperatures, verify derating requirements and consult relevant standards for fuse selection and replacement.
