Siemens 3NE8021-1 SITOR Fuse Link, NH00, 100A, aR Semiconductor Protection Original Brand New

Overview

The Siemens SITOR series is the industry standard for protecting sensitive power electronics. The 3NE8021-1 is specifically engineered to handle high-speed interruptions, safeguarding components like thyristors, power transistors, and diodes from short-circuit damage. With its blade contact design and integrated front indicator, it offers both easy installation and quick status visualization.

Key Benefit

• Ultra-Fast Response: The aR (Partial Range) switching characteristic provides superior protection against high-energy short circuits.

• Compact Footprint: The NH00 standard size allows for high-density mounting in power distribution cabinets.

• High Breaking Capacity: Safely interrupts high-fault currents at voltages up to 690V AC.

• Visual Monitoring: Equipped with a front indicator for immediate identification of blown fuses, reducing downtime.

Technical Function

• Circuit Protection: Guards power converters and rectifiers against overcurrent.

• Thermal Management: Optimized power loss characteristics to prevent overheating within the switchgear.

• Universal Compatibility: Standard blade contacts ensure fitment in all compatible NH00 fuse holders and bases.
