Fuse link - NH000 gG 32A/400V - time-lag 004181108

Knife fuse links – reliable installation protection

Knife fuse links NH are industrial devices designed to protect electrical installations against the effects of short circuits and overloads. Their construction and electrical parameters comply with PN-93/E-06160 (gF), PN-IEC-269 and VDE 0636 standards, which guarantees their reliability and safety of use. Model NH000 gG 32A/400V, thanks to its time-delay characteristic, is perfect for applications requiring tolerance to short-term overvoltages, such as starting electric motors.

Construction and characteristic features

The NH000 fuse link has been designed with durability and functionality in mind. The steatite body provides thermal stability, and the silver-plated brass knife contacts guarantee low transition resistance and minimize power losses. The aluminum covers protect against corrosion, extending the life of the device. The fuse link is filled with quartz sand of a special granulation, which translates into a high short-circuit breaking capacity – up to 120 kA – and stable electrical parameters.

It is worth paying attention to the dual operating indicator – a red eye in the central part of the ceramic body and a springy plate on the upper cover. This system ensures easy and reliable identification of a blown fuse, even in difficult working conditions. Additionally, the indicator in the upper cover allows cooperation with the NVS 5 microswitch, which enables remote signaling of the fuse link operation.

Application and benefits

The NH000 gG 32A/400V fuse link finds wide application in industrial, commercial and public utility installations. It is ideal for protecting circuits powering various types of receivers, such as:

• Electric motors
• Electrical switchboards
• Power cables
• Load-type devices

Using this fuse link translates into:

• Effective protection of the installation against overloads and short circuits
• Increased safety of use
• Long life thanks to high-quality materials and workmanship
• Easy identification of a blown fuse thanks to the dual operating indicator
• Possibility of remote signaling of operation (using the NVS 5 microswitch)
