Fuse link - NH3C gG 100A/500V - time-lag 004186214

NH Fuse Links – Reliable Installation Protection

NH knife fuse links are a proven element of electrical protection, protecting against the effects of short circuits and overloads. The design and parameters of these fuse links comply with PN-93/E-06160, PN-IEC-269 and VDE 0636 standards, which guarantees their reliability and safety. This model, designated NH3C gG 100A/500V, is characterized by a time-delay operating characteristic, which means it allows for short-term exceeding of the rated current without tripping.

Construction and application

The NH3C gG 100A/500V fuse link is designed to operate in alternating current (AC) circuits with a rated voltage of up to 500V and a rated current of 100A. The gG characteristic (full-range) provides protection against both overloads and short circuits. It is equipped with a double tripping indicator – a red eye in the central part of the ceramic body and a springy plate on the top cover – which facilitates quick identification of a blown fuse. The body made of steatite provides thermal stability, and the silver-plated knife contacts guarantee good electrical contact and minimize power losses.

Key features and benefits

• Time-delay characteristic (gG): Allows for short-term overloads, which is important when starting devices with motors or other loads with high inrush current.
• Double tripping indicator: Provides easy and quick visual identification of a blown fuse, both in the fuse base and in the disconnector.
• High breaking capacity: Guarantees effective disconnection of the circuit in the event of a short circuit.
• Made of high-quality materials: Steatite body and silver-plated contacts ensure durability and reliable operation.
• Compliance with standards: Meets the requirements of PN-93/E-06160, PN-IEC-269 and VDE 0636 standards, which confirms its safety and quality.
• Metal insulated grips (IMGL): The absence of this feature means that special caution must be exercised when replacing the fuse link.

The NH3C gG 100A/500V fuse link is a solid solution for installers and end-users looking for reliable protection of electrical installations against the effects of overloads and short circuits. Its versatility makes it suitable for various industrial and commercial applications.
