Siemens 3NA6 240-6 LV HRC Fuse Link

Description

The Siemens 3NA6 240-6 is a high-quality LV HRC (Low Voltage High Rupturing Capacity) fuse link from the SENTRON series. It is designed to provide dependable overcurrent protection for industrial installations, cables, and lines. With a rated current of 200A and a rated voltage of 690V AC, this fuse is suitable for demanding applications. Its gG characteristic makes it ideal for general-purpose protection, and the built-in front indicator allows for quick identification of a blown fuse.

FAQ

The 'gG' classification indicates a general-purpose fuse link intended for cable and line protection. It can interrupt currents from the smallest melting current up to its maximum breaking capacity.

No, 'gG' fuses are generally too slow to protect sensitive semiconductors like thyristors or IGBTs. For such applications, a fuse with a 'gR' or 'aR' (semiconductor protection) characteristic is required.

The red pin is a trip indicator. If the fuse blows due to an overcurrent or short circuit, this pin pops out. This provides a clear visual signal of the faulty fuse and can also be used to actuate a microswitch for remote signaling in a compatible fuse base.
