HHT10 Series Bar-type Vertical Fuse Switch Disconnector,Three Phase From 160A to 630A Factory Directly,Rated Working Voltage 690V
Meaning of Product Model

Normal Working and Installation Conditions
The ambient air temperature shall not exceed+40℃ and not be lower than -5℃.
The altitude of the installation site shall not exceed 2000m.
Humidity: When the maximum temperature is+40℃ , the relative humidity of the air does not exceed 50%. Higher relative humidity can beallowed at lower temperatures, such as reaching90% at20℃ . Due to temperature changesSpecial measures should be taken to treat occasional condensation.
The pollution level of the surrounding environment is level 3.
The switch should be installed in a place without significant shaking, impact vibration, and invasion of rain and snow. At the same time, theinstallation location should be free of explosive hazardous media, and there should be no gas or dust in the media that can corrode metals anddamage insulation.
Structure Characteristics
The switch is composed of a base, contacts, cover, operating handle, arc extinguishing device, etc. The base is made of unsaturated polyestermolded plastic, and the rest are pressed with arc resistant plastic. The fuse installed on the cover serves as the moving contact,The handle rotates in a fan-shaped motion along the fulcrum on the base, and the cover is connected to the fuse for opening and closing.Thebase is equipped with an arc extinguishing chamber to ensure the segmented ability of the switch. This product has a simple structure that iseasy to disassemble and assemble.
The advantages of strong arc extinguishing ability and beautiful appearance. There are two installation methods: screw fixed installation andhook fixed installation. Fixed installation with hooks, the busbar does not require punching, making installation more convenient, flexible, andreliable.
A 3-pole strip fuse holder installed on the bus track. It integrates three vertically arranged single pole fuse holders, with one contact (feedcontact) of each phase connected to one phase, and other contacts (output contact) equipped with wire connection devices.
The carrier for the live parts of the fuse holder is made of sturdy fiberglass reinforced polyester material. The silver plated fuse contacts arecombined with the tin plated lead plate to ensure low energy consumption of the product; High power acceptance and low temperature rise.
There are two installation methods: screw fixed installation and hook fixed installation.
Fixed installation with hooks, the busbar does not require punching, making installation more convenient. flexible, and reliable.
