In low-voltage power distribution systems, control and protection devices such as electrical cabinets, Reclosers, LBS, and RMUs frequently face the risk of damage from induced lightning surges or voltage spikes. The effective solution to prevent these incidents is using low-voltage surge arresters manufactured by Eaton’s Cooper – one of the world’s leading brands in electrical protection equipment.

Key Features:

• Low-voltage surge arresters are designed to prevent lightning surges and voltage spikes from damaging equipment within low-voltage electrical systems. Thanks to their fast and precise response capabilities, these products help maintain stability and safety for distribution systems, especially under grid conditions frequently affected by induced lightning surges.
• Unlike traditional surge arresters that use spark gaps, low-voltage surge arresters utilize gapless technology. This allows the device to conduct lightning surges instantaneously without requiring the mechanical switching time of traditional mechanisms. As a result, Storm Trapper can protect electrical equipment from voltage spikes immediately, without any response delay.
• A major advantage of low-voltage surge arresters is their compatibility with various types of low-voltage distribution boards, including both 1-phase and 3-phase 400V boards, as well as control cabinets for switching devices such as Reclosers, LBS, and RMUs.
• This allows engineers to easily integrate the device into most existing electrical systems without changing the overall design. Low-voltage surge arresters effectively meet protection requirements in industrial zones, commercial centers, urban infrastructure, and residential substations, ensuring maximum flexibility in practical deployment.

Practical Applications

Low-voltage surge arresters are widely used in systems such as:

• 1-phase and 3-phase low-voltage distribution boards in buildings and factories
• Recloser control cabinets at medium-voltage substations
• LBS switching device control cabinets in distribution networks
• RMU systems in industrial and commercial areas
