NH Fuse Links – Reliable Installation Protection

NH fuse links are a proven element of electrical protection, designed to protect against the effects of short circuits and overloads. The design and parameters of these fuse links comply with PN-93/E-06160 (gF), PN-IEC-269 and VDE 0636 standards, which guarantees their reliable operation and safety. Model NH3C gG 315A/690V is characterized by a time-delay characteristic, which means that it allows for short-term exceeding of the rated current without tripping, which is particularly important when starting devices with electric motors.

Construction and application

The NH3C gG 315A/690V fuse link is designed to work with appropriate fuse bases. It has a double indication of operation – a red eye in the central part of the ceramic body and a springy plate on the top cover – which facilitates quick visual identification of a blown fuse. This allows both installers and end-users to easily check the condition of the fuse link without the need for disassembly. These fuse links are used in industrial installations, electrical switchboards and wherever protection against overloads and short circuits with high current is required.

Key features and benefits

• High breaking capacity: The rated breaking capacity of the short-circuit current is 100 kA, which ensures effective protection of the installation in the event of a serious failure.
• Time-delay characteristic (gG): Allows for short-term exceeding of the rated current, which is important when starting devices with motors or other pulsed loads.
• Double indication of operation: Enables quick and easy visual identification of a blown fuse link from two sides.
• Rated voltage 690V AC: Intended for high-voltage installations.
• Rated current 315A: Suitable for circuits with high power consumption.
• Made of high-quality materials: The body made of steatite provides thermal stability, and the silver-plated knife contacts guarantee good electrical contact and minimize power losses.
• Compliance with standards: Meets the requirements of PN-93/E-06160, PN-IEC-269 and VDE 0636 standards, which confirms its safety and reliability.

It is worth remembering that choosing the right fuse link is crucial to ensure the proper operation of the electrical installation and the safety of people associated with it. The NH3C gG 315A/690V fuse link is a solid and proven solution for demanding industrial applications.
