Overview
The Siemens 3NE1021-0 SITOR Fuse Link is a high-performance semiconductor protection fuse designed for reliable overcurrent protection in industrial and power electronics applications. Featuring NH00 blade contacts, a rated current of 100 A, and gS utilization category, this fuse ensures fast and safe interruption of fault currents. It supports AC voltages up to 690 V and DC voltages up to 250 V, making it ideal for demanding electrical environments. A front-mounted indicator allows for quick visual status checks, reducing downtime and improving maintenance efficiency.
Key Benefit
-
Dual Protection: The gS characteristic covers both semiconductor protection and cable/line protection, reducing the need for multiple fuse types.
-
High Versatility: Suitable for AC (690V) and DC (250V) applications.
-
Visual Monitoring: Equipped with a front indicator for immediate status identification.
-
Compact Design: The NH00 form factor allows for high-density installation in power distribution boards.
