BUSSMANN 400NHG2B
The BUSSMANN 400NHG2B is a low-voltage NH fuse in size NH2. It is used as a fuse link in systems where cables and equipment need protection against overcurrent and short circuits. It features the classic NH type design with blade contacts, a square ceramic body, and metal gripping lugs, making it practical for use in switchboards and other fixed installations.
It is rated for 400 A and 500 V AC and is classified as gG/gL according to IEC 60269. This means it is intended for general protection of both cables and equipment in industrial installations. Its breaking capacity is 120 kA, allowing it to handle very high fault currents in the event of a serious short circuit.
Furthermore, the fuse includes a combined status indicator, allowing you to see if it has blown. It is a simple detail, but in practice, it saves time during troubleshooting and maintenance by making it easier to identify the fuse that needs to be replaced.
The fuse is stated as suitable for industry, utility plants, solar energy, and wind energy, and it is compatible with the SD2-D single-pole NH fuse base and associated accessories.
