Fuse link - NH2 gG 250A/500V - time-lag 004185232

Safe protection of electrical installations – NH2 gG 250A/500V fuse link

This industrial knife-type fuse link, catalog number 004185232, is a reliable protection against the effects of short circuits and overloads in electrical installations. Designed to operate at AC 500V and with a rated current of 250A, it provides effective protection for wires and equipment. The fuse link meets the requirements of PN-93/E-06160 (gF), PN-IEC-269 and VDE 0636 standards, guaranteeing its compliance with applicable safety standards.

### Construction and functionality

The NH2 gG fuse link is characterized by a time-delay construction (gG), which means it allows for short-term exceeding of the rated current without tripping, which is particularly important when starting devices with motors or other pulsed loads. Made of high-quality materials – a steatite body (thermally stable material) and silver-plated brass knife contacts – it ensures durability and reliable operation. Additionally, the fuse link has a dual operating indicator (KOMBI), which consists of a red eye in the central part of the ceramic body and a springy plate on the top cover. This solution facilitates quick and certain identification of a blown fuse, both in the fuse base and in the disconnector.

### Advantages for installers and users

* **Dual operating indicator:** Enables easy visual control of the fuse link status, which speeds up fault location and reduces installation downtime.

• High short-circuit interrupting capacity (120kA): Provides effective protection against serious failures and equipment damage.

• Time-delay characteristic (gG): Allows for safe starting of devices with high inrush current without unnecessary tripping of the protection.

• Made in the EU: Guarantees high quality workmanship and compliance with European standards.

• Compatibility: The fuse link is compatible with fuse bases and fuse disconnectors, making it easy to install and replace.

• Durable construction: Steatite body and silver-plated contacts ensure long life and corrosion resistance.

• Total Joule integral: A value of 812000 A²s provides sufficient energy to interrupt a short circuit.

By choosing this fuse link, you are investing in the safety and reliability of your electrical installation. It is an ideal solution for both professional installers and end-users looking for a proven protection against the effects of short circuits and overloads.
