Fuse link - NH00 gG 125A/500V - time-lag 004182215

Fuse link – reliable installation protection

Fuse insert NH00 gG 125A/500V is an element designed to protect electrical installations against the effects of overloads and short circuits. It is a proven component that meets the requirements of PN-93/E-06160 (gF), PN-IEC-269 and VDE 0636 standards. The construction and electrical parameters of the insert guarantee effective protection of wires and devices.

Construction and application

The NH00 gG insert combines the features of traditional time-delay fuses with modern solutions. The gG characteristic means that the insert provides full-range protection, reacting to both overloads and short circuits. This makes it ideal for protecting circuits powering various types of receivers where short-term current surges are permissible – for example, when starting motors. A dual operating indicator – a red eye in the ceramic body and a springy plate on the top cover – provides quick and clear information about the blown insert, making it easier to locate the fault. The "KOMBI" version with a dual indicator improves the visibility of the insert's operating status in both bases and fuse disconnectors.

Key features and benefits

• Compliance with standards: Meeting the requirements of PN-93/E-06160, PN-IEC-269 and VDE 0636 standards ensures reliable operation and safety of use.
• gG characteristic: Provides effective protection against overloads and short circuits, protecting the installation from damage.
• Dual operating indicator: Facilitates quick identification of a blown insert and fault location.
• High breaking capacity: Rated short-circuit breaking capacity of 120kA guarantees safety even in the event of serious disturbances.
• Durable construction: Body made of steatite and knife contacts made of silver-plated brass ensure stable electrical parameters and long-term reliability.
• Wide voltage range: Possibility of use in both AC 500V and DC 250V circuits increases the versatility of the product.
• Intended for wire protection: Ideal solution for industrial and commercial installations requiring reliable protection against overloads and short circuits.
• Joule integral: The high value of the Joule integral (136700 A²s) indicates the large amount of energy that the insert can absorb during a short circuit, which translates into greater installation safety.
