Single-phase surge protector for small power distribution cabinet
Product working principle
The surge protector's voltage limiting function consists of metal
oxide varistors connected in parallel. Each varistor must have an
independent detacher. The working principle of the detacher is
thermal tripping. This function is realized by dissolving the
low-temperature solder joint and disengaging the metal rod by its
own elastic action. When it is out of operation, a red indication
will be displayed in the transparent window on the front of the
surge protector. Installed in the building distribution cabinets,
outdoor distribution cabinets.
Features
1. Small size and easy installation
2. Multi-function overvoltage protection Thunderstorm overvoltage
and other disasters are no longer afraid
3. How much is the limit voltage?

product description
The Thor surge protector is designed and manufactured according to
the IEC and GB standards, and meets the IEEE802.3AT requirements.
We select brand components for the materials, use advanced
production technology, and have large flow capacity and low
residual voltage level. Responsive, stable performance, reliable
work, and so on, so that you can use the weather in peace of mind,
ease of use, no longer have to worry about the harm of thunderstorm
weather!
Structure and Principle
SPD is a port, shocking protection, indoor-mounted installation,
voltage-limited.
SPD hold disconnector inside, when SPD breakdown failure by over
heating, the disconnector can remove from the power grid
automatically, and show indication signal. When SPD is working
properly, visible window display green, it display red when it
breakdown and disconnect.
1P+N,2P+N,3P+N SPD consist of 1P,2P,3P SPD+NPE zero ground
protection module, apply to TN-S, TN-C-S and other power supply
system.
Use caution
1. The input (IN) of the lightning protector is connected to the
signal channel, and the output (OUT) is connected to the input of
the protected device. It cannot be reversed.
2. It should match the working voltage of the protected equipment.
Please connect it according to the installation diagram when
installing.
3. This product does not require special maintenance. The SPDs
should be inspected regularly, especially before the thunderstorm
season and during the entire thunderstorm period. When the system
work fails, the SPDs can be dismantled and then inspected. If the
system is restored to its original state, the system will recover.
Normally, the lightning protector is damaged and must be replaced
immediately.
Company profile
