Surge Protective Devices (SPD)

Exelcius Automation provides Type 1, Type 2, and Type 3 Surge Protective Devices of different makes.

Surge Protective Devices (SPDs) are essential electrical components designed to protect electrical systems and equipment from voltage spikes and transient overvoltages caused by lightning strikes, power surges, or switching operations.

Key Features:

• Voltage Regulation

  Limits excess voltage to prevent damage.



• Multiple Protection Levels

  Available for different applications, including industrial, commercial, and residential use.



• Fast Response Time

  Reacts in nanoseconds to divert surges safely to the ground.



• Thermal Protection

  Equipped with safety mechanisms to prevent overheating and failure.

Types of SPDs

• Type 1:

  Installed at the main service entrance to protect against direct lightning strikes.



• Type 2:

  Used at distribution panels for protection against indirect surges.



• Type 3:

  Installed at the equipment level (e.g., power strips) for localized protection.

Applications:

• Electrical panels in homes and industries.
• Telecommunication networks.
• Data centers and IT infrastructure.
• Renewable energy systems (solar and wind).

By preventing damage to sensitive equipment, SPDs enhance electrical system reliability, reduce downtime, and improve safety, making them crucial for modern power distribution networks
