Fuse link, LV, 125 A, AC 500 V, NH00, gL/gG, IEC, double indicator 125NHG00B

Low-voltage circuit protection – NH00 125A fuse link

This fuse link, catalog number 125NHG00B, is a reliable element protecting electrical installations from the effects of overloads and short circuits. Designed for operation in AC circuits up to 500V, it provides effective protection of wires and devices. Its construction based on IEC 60269-1 and IEC 60269-2 standards guarantees a high level of safety and compliance with applicable standards.

Characteristics and application

The fuse link is characterized by a gG characteristic, which means it is intended for protecting wiring and electrical equipment. Thanks to this, it reacts to overloads in a way that ensures long-term operation of the installation without unnecessary circuit disconnection. The short-circuit breaking capacity at 120 kA provides a quick response in the event of a serious failure, minimizing the risk of damage. The dual blown indicator facilitates identification of a blown fuse, which significantly shortens the time to locate and repair the fault.

NH00 fuse links are widely used in:

• Low-voltage switchboards
• Power circuits for motors and other high-current devices
• Industrial and commercial installations
• Electrical power distribution systems

Construction and product features

The fuse link is made of high-quality materials, guaranteeing its durability and reliability. Its compact design (size NH00) facilitates mounting in standard fuse holders. The lack of metal insulated grips (IMGL) simplifies installation and reduces costs. The combined indicator (dual) allows for a quick visual assessment of the fuse status – whether it has blown or not. Power losses of only 9W minimize the impact on the energy efficiency of the installation. The total Joule integral of switching is 136.7 A²s and the pre-arcing integral is 46.1 A²s, which proves high efficiency in short-circuit conditions.
