Fuse link - NH3C gG 280A/500V - time-lag 004186220

NH fuse links – reliable installation protection

NH knife 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 in various conditions. The NH3C gG 280A/500V model is characterized by a time-delay characteristic, which means that it allows for short-term exceeding of the rated current without disconnecting the circuit – an ideal solution for devices with motors or other loads with high starting current.

Construction and application

The NH3C gG 280A/500V fuse is made of high-quality materials, such as steatite (body) and silver-plated brass (contacts), which ensures thermal stability and corrosion resistance. It has a dual operating indicator – a red eye in the central part of the ceramic body and a springy plate on the upper cover – which facilitates quick visual identification of a blown fuse. This allows installers to quickly locate damage, and end users to easily check the condition of the fuse link. The KOMBI version allows cooperation with the NVS 5 microswitch for remote indication of operation.

Key features and benefits

• Time-delay characteristic (gG): Allows for momentary overloads without unnecessary disconnection of the circuit, which is important for devices with motors or other pulsed loads.
• High breaking capacity: Provides effective protection against the effects of short circuits with high currents.
• Dual operating indicator: Facilitates quick identification of a blown fuse both visually and remotely (using a microswitch).
• Durable construction: The body made of steatite and silver-plated contacts ensure long-lasting and reliable operation.
• Compliance with standards: Meets the requirements of PN-93/E-06160, PN-IEC-269 and VDE 0636 standards, guaranteeing safety and compatibility with other electrical installation elements.
• Rated current 280A at 500V AC: Adapted to protect circuits of medium power.
• Metal insulated grips (IMGL): None - no additional insulation protection of the grips.

The NH3C gG 280A/500V fuse link is a solid and reliable solution for installers and end users looking for effective protection of electrical installations against overloads and short circuits. Its versatility and ease of identifying the operating status make it a practical choice for both industrial and commercial applications.
