Protect your devices from voltage spikes with surge protectors. Learn how they work and why they’re essential.

In today's tech-heavy world, we rely heavily on electronic devices like appliances and office equipment. But these devices are at risk from electrical surges, which are sudden spikes in voltage that can damage them.

What Causes Electrical Surges?

Electrical surges can happen due to:

Lightning Strikes: One of the most powerful sources of surges, lightning can cause severe spikes in voltage that travel through power lines.

Power Outages: When the power is restored after an outage, the sudden influx of electricity can create a surge.

High-Power Electrical Devices: Appliances such as refrigerators, air conditioners, and industrial machines can cause minor surges when they are switched on or off.

Faulty Wiring: Poorly maintained or damaged wiring can lead to irregularities in voltage.

What Does a Surge Protector Do?
A surge protector shields electronic devices from voltage spikes. It blocks or redirects excess electricity above a safe level, ensuring only the right amount reaches your devices.

Types of Surge Protectors:

Class B: Class B surge protection devices are designed to provide stage 1 protection against surges in the electrical system.

Class C: Class C SPDs are typically installed at the point of use or distribution boards within a building and provide stage 2 protection against transients that are generated within the electrical system itself. 

Class B+C: Class B+C Surge protection device designed to protect low voltage distribution system against transient overvoltage by a direct and indirect lightning strike and switching operations.

Class D: Type 3/Class D Surge Protection Devices are equipped into the system for stage 3 protection. Specially designed for the protection of Power & data interface & generally equipped between the signal cable at input as well as output part of the equipment.

How Surge Protectors Work:
Surge protectors typically use components called Metal Oxide Varistors (MOVs) to divert excess voltage. When a surge occurs, the MOVs absorb and redirect the excess voltage away from the connected devices, protecting them from damage.

Why You Need Surge Protectors:

  • Protects expensive equipment
  • Prevents data loss
  • Ensures safety
  • Extends device lifespan

In Conclusion: Surge protectors are essential for safeguarding electronics from damage caused by electrical surges. They're a simple yet effective way to protect your investment in devices, data, and safety. Remember to replace surge protectors periodically to maintain effectiveness.
