Fuse link - NH3C gG 400A/500V - time-lag 004186224

Knife fuse links – reliable installation protection

NH3C gG 400A/500V fuse links are protective elements designed to protect electrical installations against the effects of short circuits and overloads. They provide effective protection of cables and equipment, acting as a key safety element in power distribution systems. The design and electrical parameters of these fuse links comply with PN-93/E-06160 (gF), PN-IEC-269 and VDE 0636 standards.

Characteristics and application

NH KOMBI fuse links, such as this model, are equipped with a dual operating indicator – both on the front and on the top cover. This solution provides very good visibility of the fuse link’s operating status, making it easier to quickly identify a blown fuse in both bases and fuse disconnectors. This allows for a quick response to failures and minimization of downtime. The KOMBI version is particularly useful where reliable protection status indication is required.

The NH3C gG 400A/500V fuse link is characterized by a time-delay characteristic (gG), which means that it allows for short-term exceeding of the rated current without disconnecting the circuit. This is important for devices with electric motors or other loads generating inrush currents during start-up. The rated breaking capacity of 120 kA guarantees effective circuit interruption in the event of a short circuit.

Product advantages

• Dual operating indicator: Enables easy and quick identification of a blown fuse from different perspectives.
• Time-delay characteristic (gG): Allows for safe operation with devices generating inrush currents, such as electric motors.
• High breaking capacity (120 kA): Provides effective protection against the effects of short circuits.
• Compliance with standards: Meets the requirements of PN-93/E-06160, PN-IEC-269 and VDE 0636 standards, guaranteeing safety and reliability.
• Made of high-quality materials: The steatite body provides thermal stability, and the silver-plated brass knife contacts guarantee good electrical contact and corrosion resistance.
• Wide range of rated voltages: Suitable for use in installations with voltages up to 500V AC.
• Universal application: Suitable for use in both industrial and commercial installations.
