Fuse link - NH2/WT-2 gF 355A/500V - quick 004139413

Installation and device safety – NH2/WT fuse links

The NH2/WT-2 gF 355A/500V fuse link is an element used to protect electrical circuits against overload and short circuit. This is particularly important in industrial installations and public buildings, where high reliability and safety are required. The design with a double operating indicator facilitates quick identification of a blown fuse, minimizing downtime of the installation.

Characteristics and application

The fuse link with gF characteristic (fast) is designed to protect against the effects of sudden current surges, such as those occurring when starting motors or short circuits. The fast response to short-circuit current allows to limit damage to the installation and connected devices. The rated current of 355A and the rated voltage of 500V AC make this fuse suitable for use in circuits with high load.

• Fast gF characteristic: ideal for protecting circuits sensitive to short-term overloads.
• Rated current 355A: enables protection of circuits with significant power consumption.
• Rated voltage 500V AC: ensures compatibility with most standard electrical installations.
• Size NH2: a popular standard, ensuring wide availability and ease of replacement.
• Double operating indicator (KOMBI): facilitates visual identification of a blown fuse – both the springy plate on the top cover and the red eye on the ceramic body indicate the need for replacement. This is a useful solution for installers who can quickly locate the problematic fuse without having to disassemble it.

It is worth remembering that proper selection of the fuse link for a specific application is crucial to ensure effective protection of the electrical installation. It is necessary to take into account the load characteristic, rated current and breaking capacity. If in doubt, it is worth consulting a specialist.
