What type of fuse is this?
The Siemens 3NE8022 is a SITOR fuse link with blade contacts, an NH00 body size, and an aR operating class. It has a rated current of 125 A and a front indicator.
What is the rated current?
The fuse link has a nominal current rating of 125 A. Selection should also account for the circuit requirements and operating conditions rather than the current rating alone.
What are the AC and DC voltage ratings?
The rated voltage is 690 V AC or 440 V DC. Use the rating corresponding to the circuit's voltage type when assessing suitability.
What fuse size does it use?
This fuse link uses the NH00 size. A replacement must match the required fuse size and contact arrangement as well as the electrical ratings.
What type of electrical contacts does it have?
The fuse link has blade contacts. Check that the existing fuse base or switch disconnector accepts the NH00 blade-contact format before selecting it.
Where is the fuse indicator located?
The indicator is located on the front of the fuse link, providing a visible indication of fuse operation.
What is the specified operating temperature range?
The documented operating ambient temperature range is -20°C to +50°C. Temperature conditions inside the enclosure should be considered when assessing the installation.
Does the fuse require a particular mounting orientation?
The documented mounting position is unrestricted, although vertical mounting is preferred. The installation must also follow the requirements of the compatible fuse base or switch disconnector.
What should be checked when selecting a replacement?
Check the 125 A current rating, the applicable 690 V AC or 440 V DC voltage rating, NH00 size, blade-contact configuration, and aR operating class. Matching dimensions and current alone is not enough to establish electrical suitability.
