Description

Overview

The Siemens SITOR 3NE3340-8 series is engineered specifically for the protection of power semiconductors such as diodes, thyristors, and MOSFETs. Unlike standard NH fuses, SITOR fuses offer a much faster response time to prevent damage to expensive electronic components during short-circuit events. The slotted blade contact design allows for secure mounting in specialized fuse bases or switch disconnectors.

Features & Function

  • Type: SITOR fuse link

  • Model: Siemens 3NE3340-8

  • Rated Current (In): 900 A

  • Rated Voltage (Un AC): 690 V

  • Fuse Class: aR (partial-range protection)

  • Design: NH2 size, slotted blade contacts

  • Front Indicator: Visual status indicator for easy monitoring

  • Durable Construction: Designed for long-term reliability in industrial environments

  • Easy Installation: Compatible with standard NH fuse bases

Benefit

  • Ultra-Fast Response: The aR (Partial Range) classification ensures high-speed clearing of faults, critical for semiconductor safety.

  • Reliable Monitoring: Integrated front indicator provides immediate visual confirmation when a fuse has blown.

  • Optimized Heat Dissipation: Designed to handle high continuous currents (900A) with minimal power loss.

  • Global Standards: Fully compliant with international NH-system standards for industrial reliability.
