Siemens 3NE3227 SITOR High Current Industrial Fuse 250 Amp Unit

Siemens 3NE3227 is a SITOR high-current fuse link designed for NH1 fuse bases, delivering overcurrent protection in industrial power systems. The unit is rated In 250 A and Un AC 1000 V, with aR characteristics and slotted blade contacts that ensure secure insertion into compatible holders. A front-indicator provides visual status when installed in fuse switch assemblies. This 3NE3227 fuse link belongs to Siemens' SITOR family, offering a replaceable protection element for high-current circuits in industrial equipment and distribution panels. It is intended for use in NH1 installations, where a rugged, replaceable fuse link is required to interrupt fault currents while enabling straightforward replacement after a fault. The combination of a 250 A nominal current rating and 1000 V AC maximum operating voltage makes it suitable for demanding industrial applications that rely on robust, serviceable protection components in power distribution and machine rooms.
