Description

Overview

The Siemens 3NA6814 belongs to the trusted SENTRON portfolio, offering superior protection for cables and lines in industrial and commercial electrical systems. As an NH000 size fuse, it provides a compact footprint without compromising breaking capacity.

The gG (general purpose) characteristic ensures that the fuse handles both overload and short-circuit protection efficiently. With its combined indicator (front and top), maintenance teams can quickly identify blown fuses, reducing downtime. The insulated grip lugs provide an additional layer of safety during installation and replacement by minimizing the risk of accidental contact with live parts.

Key Benefit

  • Enhanced Safety: Insulated grip lugs reduce the risk of electrical shock during handling.

  • Dual Monitoring: The combined indicator allows for clear visibility of the fuse status from multiple angles.

  • Versatile Application: Rated for both AC (500V) and DC (250V) networks.

  • Reliable Protection: Proven gG tripping characteristic for comprehensive line and device protection.

  • Compact Design: The NH000 form factor allows for high-density installation in distribution boards.

Technical Function

  • Overload Protection: Safely interrupts sustained overcurrents that could damage insulation.

  • Short-Circuit Protection: Instantaneous interruption of high-magnitude fault currents.

  • Status Signaling: Integrated mechanical indicator flips upon activation.
