The Siemens 3NA3817-6KJ is a SENTRON low-voltage HRC fuse link designed for reliable circuit protection in industrial electrical installations. Rated at 40 A, it features a gG operating class and supports operating voltages up to 690 V AC or 250 V DC. Its NH000 format, silver-plated blade contacts and non-insulated live grip lugs provide compatibility with suitable fuse bases and switching devices.
A front-mounted indicator allows straightforward identification of fuse operation. The fuse offers a rated breaking capacity of 120 kA AC and 25 kA DC, providing effective interruption of high fault currents. With a compact 21 mm width, IP20 protection when conductors are connected and a power loss of 3.6 W at rated current, the 3NA3817-6KJ is suited to distribution boards, control panels, machinery and drive protection applications.

What type of electrical component is this?
It is a SENTRON low-voltage, high-rupturing-capacity fuse link designed to protect electrical circuits and equipment against overloads and short circuits.
What fuse size does this model use?
The fuse link is an NH000 size in accordance with EN 60269-1.
What is the rated current?
The 3NA3817-6KJ has a rated current of 40 A.
What operating class does the fuse link have?
It has a gG operating class, making it a general-purpose fuse link with full-range breaking capability for cable, conductor and equipment protection.
What voltage ratings does it support?
The fuse link is rated for operating voltages up to 690 V AC and 250 V DC.
What is its breaking capacity?
Its rated breaking capacity is 120 kA for AC applications under IEC 60269. For DC applications with a time constant of no more than 10 ms, the rated breaking capacity is 25 kA.
Does the fuse link include a status indicator?
Yes. It includes a front-mounted indicator that provides a visible indication of the fuse condition.
What type of electrical contacts does it have?
It uses blade contacts with non-corroding, silver-plated contact surfaces to provide a dependable electrical connection.
How is the fuse link handled during installation or replacement?
The unit is fitted with live grip lugs. Suitable NH fuse-handling equipment and the correct isolation procedures should be used by a qualified electrical professional.
What is the power loss at rated current?
The specified power loss is 3.6 W per pole at the rated AC current when operating in a hot condition.
What are its physical characteristics?
The enclosure is 21 mm wide, and the fuse link has a net weight of approximately 131 g.
Can it be mounted in any position?
Yes. It can be installed in any mounting position, although a vertical orientation is preferred.
What operating temperature range is specified?
The stated ambient operating temperature range is from -5 °C to 40 °C.
What level of ingress protection is provided?
The fuse link is rated IP20 when the conductors are connected correctly.
Can it be used with a SINAMICS G120X converter?
It is listed as a recommended 40 A IEC fuse for selected SINAMICS G120X 690 V configurations, including a 22 kW frame-size FSD application. The complete converter reference, supply voltage and installation requirements should be checked before selection.
What should be checked before fitting a replacement fuse link?
Confirm the NH000 size, 40 A current rating, gG operating class, required AC or DC voltage rating, breaking capacity, holder compatibility and circuit design requirements. The replacement should match the electrical and mechanical specifications of the original installation.
