Overview
The Siemens 3NE1022-0 belongs to the renowned SITOR series, specifically engineered to protect sensitive power semiconductors from the effects of short circuits. Unlike standard fuses, SITOR fuses offer an ultra-fast response time, ensuring that converters, rectifiers, and thyristor-controlled systems remain undamaged during electrical faults. This model features a front indicator for quick visual status identification.
Benefit
-
Precision Protection: Designed with a gS operational class, providing full-range protection for cables and semiconductors.
-
High Breaking Capacity: Safely interrupts high-fault currents at voltages up to 690 V AC.
-
Compact Integration: The NH00 design allows for high-density installation in standard LV HRC fuse bases.
-
Minimal Power Loss: Optimized internal resistance reduces heat generation within the switchboard.
Function
-
Semiconductor Protection: Rapidly disconnects the circuit to prevent thermal overload in diodes and SCRs.
-
Dual-Voltage Versatility: Rated for 690 V AC and 250 V DC applications.
-
Visual Monitoring: Equipped with a front-mounted indicator for immediate fault detection without the need for testing tools.
