LT-60 Series Type 2 Heavy Duty Surge Protector 160kA
A Type 2 surge protection device that is put in place at the level of the distribution board so that it clamps switching and the effects of induced lightning before they affect downstream equipment Leitai Electric is a manufacturer and supplier of surge protection devices based in China with resources in OEM, wholesaler and distributor programs around the world.
Applications & circuit protection
LT-60 to LT-160 is used in places where heavy duty Type 2 protection is needed for industrial and commercial installations with energy consumption of up to 160kA Imax. These installations are often used for the following purposes.
- Heavy industry: High energy industrial supply protection.
- Main switchboards: Large capacity incoming protection.
- Data centres: High availability facility power.
- Infrastructure: Water, rail and utilities.
Schematic Diagram
The schematic diagram provided illustrates the various connection methods and the internal protection circuit of the surge protective devices having ratings from LT-60 to LT-160.
Construction & operating reliability
The LT-60 to LT-160 is made of high energy MOV components and an internal thermal disconnector, thus ensuring good clamping characteristics, as well as long lifespan. Specialized production facilities and dedicated quality control procedures at every stage of production guarantee consistent output of surge protection devices.

Heavy Duty Surge Protector Buyer FAQ: What You Need to Know
Where should the LT-60 to LT-160 be installed?
The installation of LT-60 to LT-160 should take place in the DIN rail of the distribution board, either main or sub-distribution, very close to the point where the incoming supply connects. The leads to earth must be kept short at that place.
What do In and Imax mean?
In refers to the nominal discharge current (8/20us) that is applicable for continued use; Imax refers to the maximum discharge current that can be tolerated by the SPD only.
Which earthing systems does it support?
it supports TN, TT and IT type systems depending on the configuration mode that the system supports.
Can I order samples for testing?
Yes. Samples, OEM/ODM support and wholesale pricing for B2B customers are offered.
Does the LT-60 to LT-160 have a failure indicator?
Yes, the device has visual end of the life indicator along with internal thermal disconnect material.
