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. In particular, the NH3C gG 250A/690V fuse link 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 characteristic features

NH KOMBI fuse links are distinguished by a dual operating indicator – both the front indicator and the one on the top cover signal the blown fuse simultaneously. This solution ensures easy and quick identification of the damage, even in difficult conditions. Additionally, the KOMBI version allows for good visibility of the fuse status both in bases and in fuse disconnectors. The body made of steatite provides thermal stability, and the silver-plated knife contacts guarantee low contact resistance and long-term reliability. This fuse link has a rated voltage of AC 690V and a rated current of 250A.

Application and benefits

The NH3C gG 250A/690V fuse link is used in industrial installations, public buildings and anywhere where reliable protection against overloads and short circuits is required. Its versatility makes it an ideal choice for both professional installers and end users. Thanks to the high breaking capacity (up to 100 kA) and precise time-current characteristics, this fuse link provides effective protection of the electrical installation and minimizes the risk of failure. Additionally, the presence of two operating indicators facilitates quick location of the damage and reduces installation downtime. It is also worth mentioning the possibility of cooperation with the NVS 5 micro-switch for remote signaling of the fuse operation.
