25kA 4P Type 1 Surge Protection Device Product Description:
BR-25GR shape and installation series surge protector is suitable for AC 50Hz/60Hz, 380V and other power supply systems can be used as equipotential connection for lightning strikes.
Devices have indicators to advise end of life of the device
The shell design is installed on the 35mm electronic rail.
No resetting of SPD required, the excess voltage is quickly taken to earth, before the rest of the circuits are damaged
When the breakdown fails, the failure release device can automatically detach it from the grid.

Installation:
• Used in the lightning protection zones concept at boundary LPZ0B-LPZ1.
• Suitable as the first step of protection in incoming power supply panels and areas with greater exposure to the atmosphere, where installations are usually provided with an external lightning protection system.
• Type 1 is placed at the entrance point of the installation, in the main distribution board for a global protection of this installation.
Type 1 SPD:
• The Type 1 SPD is recommended in the specific case of service-sector and industrial buildings, protected by a lightning protection system or a meshed cage.
• It protects electrical installations against direct lightning strokes.
• It can discharge the back-current from lightning spreading from the earth conductor to the network conductors.
• Type 1 SPD is characterized by a 10/350 µs current wave.
Advanced Surge Protective Device (SPD) for Reliable Power Safety
Common examples of SPD use include protecting HVAC systems, solar power setups, data centers, and sensitive electronics-ensuring uniterrupted operations during lightning strikes or grid fluctuations.
How to install SPD: Installation is quick and user-friendly. Simply mount the device near your main electrical panel, connect it to the grounding system, and integrate it with your circuit breaker.
While competitors like JPD SPD focus on basic surge suppression, our SPD outperforms with multi-stage protection, real-time status monitoring, and a self-diagnostic alert system.
