Siemens 3NA3832 Three-Phase Motor Overload Relay

Siemens 3NA3832 is a low-voltage HRC fuse element in the NH00 format, designed to protect electrical circuits in Siemens LV fuse systems. This 125 A NH00 fuse element (gG type) is rated for up to 500 V AC or 250 V DC and features a front indicator and live grip lugs for straightforward installation and replacement in compatible fuse carriers. As a standalone element, it requires a matching NH00 fuse holder to form a complete protective device in motor feeders, control panels, and distribution circuits. The 3NA3832's high-rupturing capability (HRC) helps interrupt fault currents quickly while limiting arcing, aligning with standard LV protection practices for motors and transformers in low-voltage networks. The product is part of Siemens' SENTRON LV fuse range, offering modular, plug-in protection within compact switchgear and motor control centers. Use of this fuse element is intended for installations where proven NH00 components and compatible carriers are used, ensuring reliable overcurrent protection in Siemens equipment.
