## Summary description

NH00 fuse insert by Eti-Polam, model WT-00 (004114340), rated 125 A with gF characteristic for combined protection and 500 V voltage rating. Designed as a replaceable fuse element for NH00 fuse holders and switchgear, it provides overcurrent and short-circuit protection in low-voltage distribution circuits in industrial and commercial installations.

## Long description

NH00 fuse insert by Eti-Polam, model WT-00 is a replaceable NH00-size fuse element rated for 125 A and 500 V with a gF (general fuse) characteristic. It is intended for use in low-voltage distribution switchgear and NH00 fuse holders to provide combined protection against overloads and short circuits in industrial and commercial electrical installations. The compact NH00 form factor allows straightforward replacement in standard NH00 compartments and ensures compatibility with devices designed for NH00 fuse inserts.
Advantages
The fuse insert has a gF characteristic that enables coordination between overload protection and fault interruption, making it suitable for protecting cables and motor circuits where both slow heating and high short-circuit breaking capacity are required. Its 125 A rating supports medium-current circuits and the 500 V voltage capacity covers a wide range of low-voltage distribution applications. As a replaceable NH00 element, it simplifies maintenance and reduces downtime in switchboards and distribution panels.
Подходит для
 Защиты силовых линий в промышленном и коммерческом распределении
 Защиты кабелей и моторных цепей, требующих комбинированного (gF) характера работы
 Встраивания в щитовое оборудование и NH00-патроны для быстрой замены
Key specifications
 Rated current: 125 A
 Rated voltage: 500 V (suitable for low-voltage distribution)
 Fuse characteristic: gF (general fuse for combined protection)
 Size / form factor: NH00 replaceable fuse insert
How to use
Install the NH00 fuse insert into a compatible NH00 fuse holder or switchgear compartment that accepts NH00 elements. Ensure the power to the circuit is disconnected and locked out before removing the old insert and fitting the new one. Verify the fuse orientation and seating in the holder so electrical contacts are secure. After installation, restore power and check the circuit for correct operation and absence of abnormal heating or noise.
Использование и рекомендации
Перед заменой всегда отключайте питание и следуйте процедурам безопасности в электромонтаже. Подбирайте номинал и характеристику предохранителя в соответствии с характеристиками цепи и рекомендациями по селективности для обеспечения надежной защиты.

The compact NH00 form factor allows straightforward replacement in standard NH00 compartments and ensures compatibility with devices designed for NH00 fuse inserts.
Advantages
The fuse insert’s gF characteristic provides reliable interruption of short-circuit currents while allowing appropriate response to overloads, facilitating selective protection when coordinated with upstream or downstream devices. With a 125 A rating and 500 V capability, the insert suits a range of low-voltage applications. The standard NH00 sizing simplifies stocking, replacement, and maintenance operations in panels and distribution boards.
Suitable for
 Power distribution circuits in industrial and commercial installations
 Protection of cables and motor feeders where combined gF protection is required
 Replacement in NH00 fuse holders and low-voltage switchgear compartments
Key specifications
 Rated current: 125 A
 Rated voltage: 500 V
 Fuse characteristic: gF (combined overload and short-circuit protection)
 Size: NH00 replaceable insert
How to use
Before installation, isolate the circuit and follow lock-out/tag-out procedures. Remove the holder cover or fuse carrier and extract the spent NH00 insert. Fit the new NH00 insert into the holder ensuring correct seating and contact with the terminals. Replace covers and restore power, then monitor the circuit for normal operation. Use appropriate personal protective equipment when handling live enclosures and follow local safety standards.
Usage recommendations
Select the fuse rating and characteristic to match conductor sizes and upstream protection; confirm coordination studies where required. Regularly inspect fuse holders and contacts for signs of corrosion or overheating and replace worn components to maintain reliable protection.
