Siemens 3NE1022-0 SITOR Fuse Link NH00, 125A, 690V AC / 250V DC Original Brand New

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.
