The Siemens 3NA3805 is a high-quality low voltage high rupturing capacity (LV HRC) fuse element designed to provide reliable overcurrent protection in industrial settings. This component is part of the SENTRON protection device range and is characterised by its robust construction and dependable performance.

Crafted with precision, the 3NA3805 fuse element is rated for 16 A and is suitable for systems with supply voltages up to 500 V AC and 250 V DC. It features a gG operating class, which indicates it is designed for both overload and short-circuit protection, making it a versatile choice for a wide range of applications.

The fuse element is of the NH000 size, conforming to DIN EN 60269-1 standards, ensuring compatibility with standardised fuse holders and accessories. The design includes non-corroding, silver-plated blade contacts for a secure and long-lasting electrical connection.

One of the key features of the 3NA3805 is its front indicator, which provides a clear visual indication when the fuse has operated, allowing for quick identification and replacement. The fuse link is also designed with live grip lugs, facilitating safe and easy handling during maintenance.

With a switching capacity of 120 kA according to IEC 60947-2, this fuse element can handle significant fault currents, providing robust protection for electrical circuits. The power loss is minimised at 1.7 W per pole in a hot operating state, ensuring energy efficiency.

The 3NA3805 operates within an ambient temperature range of -5 °C to +40 °C and is rated for a climatic category of -20 to +50 at 95% relative humidity, making it suitable for challenging environmental conditions.

This LV HRC fuse element is an essential component for professionals seeking a reliable and efficient solution to protect electrical equipment from overcurrents in commercial and industrial installations.
