3NE1803-0

Siemens' part number 3NE1803-0 is a robust industrial fuse link featuring blade contacts. This unit is specifically categorized in the NH000 fuse system size, compliant with EN 60269-1 standards. It supports a rated current of 35 A and is capable of functioning at voltage ratings of 690 V for AC and up to 250 V for DC operations. This design is particularly appropriate for applications where general-purpose semiconductor protection is necessary, as indicated by its gS operating class classification.

In terms of overcurrent protection, the 3NE1803-0 demonstrates a breaking capacity of 100 kA according to IEC 60947-2 regulations. Under rated conditions, it experiences a maximum power loss measured at 3.5 W. Silver-plated blade terminals serve as the contact material, ensuring efficient conductivity and durability.

A front-mounted visual indicator simplifies fuse status assessment, enhancing user convenience during maintenance checks. The mounting configuration is compatible with low-voltage HRC fuse bases and switch disconnectors, allowing for flexible installation options. The fuse link operates effectively within a temperature range of -20°C to +50°C while also performing reliably in environments with up to 95% relative humidity. With its weight at 134 grams and a load factor of 1, the fuse can be mounted in any orientation, although a vertical position is preferred for optimal performance.
