Description

Overview

The Siemens 3NA3807 (LV HRC system) is a critical component in industrial electrical installations. As part of the Sentron protection device family, this NH000 size fuse element provides comprehensive protection against short circuits and overloads. Its robust design and "gG" operational class make it a versatile choice for general-purpose cable and line protection.

Key Benefit

  • Enhanced Safety: Equipped with a high breaking capacity to safely interrupt electrical faults.

  • Visual Status Monitoring: The integrated front indicator allows for immediate visual identification of tripped fuses, reducing downtime.

  • Ease of Handling: Features live grip lugs, making it compatible with standard NH fuse pullers for quick replacement.

  • Durable Performance: Siemens quality ensures long-term aging resistance and precise tripping characteristics.

Function & Specification

  • Protection Class (gG): Full-range protection for general applications (cables and lines).

  • Dual Voltage Rating: Optimized for 500V AC and 250V DC systems.

  • Compact Design: The NH000 size (LV HRC) saves space in distribution boards and switchgear.

  • High Breaking Capacity: Ensures the protection of downstream components during high-current faults.
