Fuse link - NH000 gG 40A/500V - time-lag 004181210

NH000 gG 40A/500V fuse – reliable installation protection

This knife-type fuse, marked NH000 gG 40A/500V and catalog number 004181210, is a key protective element in industrial installations. Designed to protect against the effects of short circuits and overloads, it meets the requirements of PN-93/E-06160 (gF), PN-IEC-269 and VDE 0636 standards. It is a product of ETI Polam, a renowned manufacturer of electrical components.

Construction and application

The NH KOMBI fuse is characterized by a unique solution – double tripping indicator. The combination of an indicator on the top cover (resilient metal plate) and in the central part of the ceramic body (red eyelet) provides a clear and easy-to-read indication of the fuse blowing. This feature is particularly useful both in standard fuse bases and in fuse disconnectors, facilitating quick identification of the damaged element. The KOMBI version ensures good visibility of the fuse operating status.

This fuse is ideal for protecting cables with gG characteristics – i.e. general purpose, providing protection against overload and short circuit. Its rated current of 40A at 500V AC makes it suitable for many industrial and energy installations.

Key features and benefits

• High breaking capacity: Rated short-circuit breaking capacity of 120kA guarantees effective protection of the installation even with high short-circuit currents.

• Double tripping indicator: Facilitates quick identification of a blown fuse, minimizing installation downtime.

• Durable construction: The body made of steatite (thermally stable material) and silver-plated knife contacts ensure reliable operation and long life.

• Versatile application: Suitable for protecting cables with gG characteristics, providing comprehensive protection of the electrical installation.

• Compliance with standards: Meets the requirements of IEC 60269-1 and IEC 60269-2 standards, confirming its safety and quality.

• Indicator compatible with signaling: The indicator on the top cover allows cooperation with the NVS 5 microswitch for remote fuse tripping signaling.

Additional information: The total Joule integral of switching is 16000 A²s, and the pre-arcing 3300 A²s, which proves the high energy efficiency of this product. Power losses are 3.4W. The fuse has a double (combined) indicator.
