M-SP series surge protection deviceDetailed product description：

Description of M-SP series surge protection device

This series of products is suitable for lightning and surge protection in the PZOB lightning protection zone and the LPZ1 to LPZ2 (Class C or II) power lines.
The core component of this product adopts the latest high-capacity surge absorber MOV, which has been rigorously screened and has stable quality.
The product has the advantages of high current capacity, low output residual voltage, and fast response to overvoltage (action time less than 25ns), which can effectively protect electrical equipment.
Install a failure release device that can automatically disconnect the protector from the power grid when it fails due to overheating or breakdown.
This series of products has complete functions, modular packaging, and standard 35mm wide electrical installation rails for easy installation and replacement.
The shell is made of reinforced flame-retardant PBT material, which meets electrical safety standards.
Can attach alarm remote signaling

Product installation location and application
The C-level module series is usually installed at the junction of LPZOB or LPZ1 area or LPZ2 area, that is, Class II, and is usually installed in distribution cabinets and boxes.
Combining single poles into various configurations, suitable for TN-S, TN-C, TN-C-S, TT, IT and other power supply systems.
Widely used for second level lightning protection in power supplies. Usually installed at the distribution cabinet; Floor distribution boxes, computer centers, telecommunications rooms, security monitoring centers, cable TV rooms, building control rooms, elevator control rooms, fire control centers, industrial control hospital operating rooms, monitoring rooms, and distribution boxes containing electronic medical equipment; It can also be installed in the main distribution box of residential buildings below six floors and in the distribution box of dispersed villas.
Before the surge protector, a commercially available 63A fuse must be installed as a backup safety device for the protector.
The protector is suitable for indoor installation, and waterproof measures should be added outdoors.
All wiring must ensure firm and reliable electrical connection, and lightning protection grounding should comply with lightning protection specifications (recommended grounding resistance not exceeding 10 Ω), and the grounding wire should be short and straight (≤ 0.5 meters). The wire diameter specifications are shown in the wire specification table.
