Fuse link - NH000 gG 63A/400V - time-lag 004181112

Knife fuse links – reliable installation protection

Knife fuse links of the NH series are industrial devices designed to protect electrical installations against the effects of short circuits and overloads. Their design 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. This model, designated as NH000 gG 63A/400V, is a proven protection element that will find application in both industrial installations and public buildings.

Characteristics and application

The NH000 gG 63A/400V fuse link is characterized by a time-delay gG characteristic, which means it is designed for general use and provides protection against overloads and short circuits. The rated current of 63A at 400V AC makes it ideal for protecting circuits with medium power. Additionally, a combined type operation indicator (double) – on the top cover and in the central part of the housing – ensures quick and easy identification of a blown fuse. This facilitates locating the damage and reduces installation downtime.

Construction and advantages

The fuse link is made of high-quality materials: a steatite housing (thermally stable material), silver-plated brass knife contacts and aluminum covers. The housing tightly filled with quartz sand of a special granulation ensures a high short-circuit breaking capacity – up to 120kA – and stable electrical parameters. Silver-plated knife contacts facilitate mounting in a fuse base or fuse disconnector. Two operation indicators increase user comfort and enable cooperation with the NVS 5 microswitch for remote burnout signaling. All this translates into long-lasting and trouble-free operation of the device.
