High breaking capacity,knife-shaped contact fuse

Product Description

Scope of application

Rt16 fuse can replace NT fuse,using in low-voltage power distribution network.It is mainly used for protecting the electric circuit and cable from overload or short circuit,as well as protecting electric equipment.

Application case:

Low-voltage power distribution panel;

Fuse-combination units;

High demand radial and grid based power network;

Motor circuit;

Short circuit protection for contactor and breaker;

Back-up protection for contactor and breaker;

Standard:GB/T 13539.2-2008,IEC 60269-2:2006


Structure Characteristics

Fuse base is made from DMC UPR(unstarated polyester resin)glass fiber reinforced plastic.DMC plastic with superior integrated performance,not only have high mechanical strength,but also it have good thermostability,anti-aging resistance,and fire resistance.

Good performance in 960 degree fire hazard testing and comparative tracking index testing.The DMC base reaches all standard requirement,also has attractive appearance and light wieght.This RT-16 series base is the developing and replacing product of NT series.

Fuse is made up of fuse-link and fuse base,conveniently and safely plugging fuse-link in or out of fuse base by handle.There are seven size of fuse-link,six size of fuse base,000 and 00 fuse-link use the same fuse base(00 fuse base).Fuse base is made up of insulation base and socket.


Product Characteristics

Rt 16 fuse has stable protection performance.From the characteristic curves,user can select the best matched fuse-link.

RT16 fuse has extra high breaking capacity(120kA/500V),no matter how many years passed,its breaking capacity will keep the same.It is suitable for different low-voltage power distribution network.

Customers can choose accessories from our wide portfolio.It can effectively avoid contacting with live part and ensure the safe operation.

Fuse-link has strong current-limiting capacity.It can greatly reduce the requirements for network's dynamic and thermal stability,reduced investment of grid construction.

The fuse is not only with small size,but also no harmful external effects happen when it is fusing,making the mounting area and volue very small.

For the fuse more than 16A,the ratio of the rated current betwwen up and down circuit not less than 1.6:1,it can reduce temperature rise,improving operation environment and the reliability of operation.(See following table)
