Siemens 3NE4122 Fuse

Siemens 3NE4122 is a SITOR fuse link for low-voltage protection with blade contacts and NH0 mounting, rated for 125 A and suitable for up to 1000 V AC or 440 V DC, with a front indicator for quick fault status checks. Designed for use with SITOR semiconductor fuse bases in LV HRC fuse bases or switch disconnectors, this 3NE4122 fuse link is part of Siemens' LV protection family. Its 125 A nominal current rating and dual-voltage capability reflect its role in safeguarding circuits in distribution panels and industrial equipment, while the blade-contact design enables secure, straightforward installation and replacement in compatible fuse bases. The front indicator provides at-a-glance confirmation of fuse status during maintenance or testing, and the device is explicitly described as a Low-Voltage HRC fuse link in Siemens documentation. Compatible with Siemens LV fuse systems and the 3NE family of fuse links, 3NE4122 is used where reliable overcurrent protection is required for circuits operating at up to 1000 VAC or 440 VDC.
