SIEMENS 3NA6 240-6 690V 200A

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 What does the ‘gG’ characteristic signify for this fuse?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. Is this 3NA6 240-6 fuse suitable for protecting semiconductor devices?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. What does the red pin indicator on the front mean?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.
