Scope of application
The NT/NH2 fuse links low-voltage H.R.C. fuse has the characteristics of light weight, small size, low power loss, and high breaking capacity. This product has been widely used for overload and short circuit protection in electrical installations. This product complies with the IEC 60269 standard
Zhejiang Xinda Electric Co., Ltd., also known as Huaxing Fuse Factory, has been developing and producing fuses for more than 30 years since 1989. We have our own accessory production workshop and finished product workshop, and the application of NT/NH2 fuse links meets the NH HRC fuse IEC60269-2 safety standard. It mainly consists of a cover plate, a plug, a knife contact, a fuse element, a filler, and a ceramic body,

Here are some important notes on the use of fuses:
Working conditions
Normal working conditions and correction parameters
The fuse operates under the following normal usage conditions and does not require additional modifications.
When exceeding normal usage conditions, if within the allowable usage range, some parameters may need to be adjusted or consulted. If it exceeds the allowed usage conditions,
You should consult our company and conduct a job adaptability assessment and testing of the conditions. The recommended long-term current value should not exceed 80% of the rated current.
Ambient air
Normal condition
-5 ℃ to 40 ℃.
Permitted conditions for use
-40 ℃ to 120 ℃.
Parameter correction for changes in ambient air temperature: When operating below -5 ℃, the fuse should be low
The pre arc time of double overload overcurrent is slightly extended, and the rated current is slightly increased. But unless
-Above 5 ℃ is not within the working range, and generally, it is not considered to increase the rated current of the fuse.
When the fuse operates above 40 ℃, additional correction is required for the rated current, with a correction factor
For KT.
Note 1: The value of Kt has taken into account the rated current of the fuse under normal operating conditions
The impact of safety margin.
Note 2: The ambient air temperature needs to last for 1-2 hours or more to have a significant impact.
