Surge Protection Devices (SPD): Safeguard Your Electrical Systems from Voltage Surges

Surge Protection Devices (SPDs) are designed to protect electrical equipment and systems from harmful voltage spikes and surges caused by lightning strikes, switching operations, or electrical faults. These devices absorb and divert excess energy, ensuring that sensitive electronic components remain unharmed. SPDs are crucial for protecting both residential and industrial equipment, providing reliable defense against electrical surges and enhancing the longevity of your electrical systems


Features:

  • Effective Surge Protection: Absorbs and diverts voltage surges to protect electrical systems from damage.
  • Multi-Level Protection: Available in three types (Type 1, 2, and 3) for comprehensive protection at different stages of the electrical system, from the main supply to individual appliances.
  • Fast Response Time: Reacts to voltage surges in less than 25 nanoseconds, ensuring your system remains safe during surges.
  • High Discharge Capacity: Handles large current spikes caused by lightning and electrical faults, protecting even in extreme conditions.
  • Easy Installation: DIN rail or panel-mounted design makes installation quick and simple.
  • Visual Status Indicator: Provides a clear indication of device health and whether replacement is needed.
  • Long Lifespan: Built with durable materials and engineered for high endurance in industrial and residential settings.
  • Versatile Application: Compatible with a wide range of electrical installations, including commercial buildings, data centers, and homes.
  • Safety Compliance: Conforms to international standards for surge protection, ensuring maximum safety and performance.
