Siemens 3NE1334-2 is a SITOR fuse linkage with NH2 blade contacts, rated for 500 A, designed to protect Siemens SITOR fuse systems in low-voltage power-distribution and drive cabinets. It is rated for 690 V AC and 440 V DC, with a gR classification indicating high rupturing capacity, and uses blade-type NH2 insertions for secure, quick installation. The compact unit measures approximately 73 × 60 × 72 mm, making it suitable for space-constrained fuse-switch arrangements in equipment such as SINAMICS drive cabinets and other Siemens-protected assemblies.
