Product Description
Surge protection device to prevent lightning surge voltage in low-voltage electrical system or solar energy system (photovoltaic power supply system). These devices must be installed in parallel on the low-voltage distribution system or DC power supply system to be protected, and provide common and different modes of protection. Its installation location is recommended to be located at the front end of the household side of the distribution system or at both ends of the DC power line (solar panel side and inverter/converter side), and equipped with matching circuit breakers or fuses
Product Features1. T2, T1+T2 surge protection devices are available for photovoltaic/low-voltage power system.
2. Module design, easy installation, and replaceable.
4. The color of the visible window indicates the running status, green indicates normal, and red indicates abnormal.
5. No leakage, no working current.
6. Remote signal or intelligent monitoring module (optional).

A brand new exterior structural design, novel and unique, with good contact performance and large flow capacity,
which is different from other ordinary products in the market.
The maximum lightning protection capacity of a single module can reach (8/20us) 80kA, (10/350us) 12.5kA
A brand new color recognition system with a strip recognition system on the surface of the product,
which can facilitate customers to quickly distinguish the types of various products,
Products can achieve visual tracking, and each product base is equipped with a QR code recognition system.
By scanning with a mobile phone, the factory test data, model, date, batch, etc. of each product can be traced,
strictly controlling the quality and consistency of each product.
No external detachment device is required, and the detachment device can be installed with reliable interruption,
achieving complete isolation and concealment after tripping,
and self extinguishing of the arc,
effectively avoiding the phenomenon of wire drawing
Replacement can be carried out without interrupting system operation.
Pressing the contacts on both sides of the module allows for easy insertion and removal.
It has a foolproof design, self-locking function, and is easy to maintain
We have installed arc insulation plates between each phase and between the wiring connections, effectively preventing the occurrence of arc pulling and flying between phases, greatly ensuring the stability and reliability of the product,
Each product can add remote signaling terminals/intelligent monitoring modules as needed to measure and monitor the current/working status of each circuit, remotely record and display the operating status, and can be monitored through mobile phones or computers,
Different combination methods can be selected according to different power distribution systems,
with small product volume. Additionally, four wire products can be provided,
which can be used as two two two wire products
