Surge Protection Devices

Surge protection devices (SPDs), also called surge protectors, are crucial modern electrical installation devices designed to protect against transient overvoltages, commonly called power surges or spikes. These devices are installed within distribution boards or in separate enclosures and come in various types. Without proper protection, surges can inflict significant damage to sensitive electronic equipment, causing malfunctions, data loss, or even complete failure. SPDs effectively divert excess voltage from electrical installation, channelling it safely to the ground and preventing it from reaching your valuable devices. 

Why Buy Surge Protection Devices?

Investing in surge protective devices is a proactive measure to safeguard your investments and ensure business continuity. By preventing damage caused by surges, SPDs minimise downtime, reduce repair or replacement costs, and protect valuable data. In the long run, the cost of surge protection is far outweighed by the potential losses from unprotected electrical and electronic equipment.    

View Our Range of Surge Protection Devices:

We offer a comprehensive range of SPDs to meet the diverse needs of our customers. Our collection includes: 

  • Industrial Surge Protectors – Industrial surge protectors are designed for robust protection in demanding industrial environments. They can handle high-energy surges and safeguard critical equipment in manufacturing, processing, and other heavy-duty applications. A surge protector is made of robust materials to protect against EMI and RFI, ensuring uninterrupted operations. 
  • Surge Arrestors – Surge arrestors are devices specifically designed to protect against lightning-induced surges. They offer a high level of protection for installations in areas prone to lightning strikes. Also called a lightning arrestor, a surge arrestor is a vital component in substations, renewable energy systems, and high-voltage installations. 
  • Type 2 Surge Protection Devices – Our range of type 2 surge protective devices are installed at the main distribution board or sub-panels. These devices provide a second line of defense against surges, further limiting the voltage reaching sensitive equipment within the building. 

Typical Uses of Surge Protective Devices:

SPDs find applications in a wide range of settings, including:

  • Residential Settings 
  • Commercial Sectors 
  • Industrial Facilities  
  • Telecommunications
  • Renewable Energy Systems
  • Healthcare Facilities.
