Surge Arrestor: Protect Your Equipment from Voltage Surges
Surge arrestors are essential for protecting electrical and electronic systems from harmful voltage surges and transient spikes. These sudden spikes can be caused by external events like lightning strikes or grid switching, as well as internal sources such as switching equipment. Without protection, these surges can cause significant damage to sensitive equipment, including AC/DC drives, PLC, communication systems, and other critical infrastructure. Surge arrestors work by redirecting excess voltage safely to the ground, preventing equipment failures, costly downtime, and expensive repairs. They are suitable for a wide range of applications, including:
- Mains power supplies (including UPS systems)
- Data and communication cables (LAN, telephone, telemetry)
- Signal and control lines
- Industrial equipment (drives, PLC)


How Do Surge Arrestor Work?
When a transient voltage spike occurs, the surge arrestor absorbs the excess energy and safely diverts it to the ground, ensuring that only the required voltage reaches your equipment. This protection is crucial for maintaining system stability and preventing damage from brief but powerful surges, which can peak as high as 100,000 volts from lightning, 10,000 volts from grid switching, or 6,000 volts from switching inductive loads.
The Impact of Voltage Surges and Transients
Surge transients are brief but powerful voltage spikes that can last only a few microseconds. Despite their short duration, these events can cause significant damage if left unprotected. The typical causes of transients include:
Lightning strikes
: Can produce spikes as high as 100,000 volts.
Utility grid switching
: Can create surges of up to 10,000 volts due to grid operations.
Inductive load switching
: Can cause surges of around 6,000 volts when motors or other inductive loads are turned on or off.
Internal switching events
: Even internal faults or switching activities within a facility can create smaller, yet damaging, surges of around 2,000 volts.These transients, though brief, can cause severe disruption to industrial and commercial equipment, leading to unplanned downtime, system malfunctions, or even permanent damage to your electronics.


Ensure Long-Term Protection with Surge Arrestors
By installing surge arrestors at key points in your electrical system—such as power lines, communication cables, and industrial control systems—you can significantly reduce the risk of damage caused by voltage spikes. Surge arrestors help keep your systems running smoothly, extend the life of your equipment, and save you from costly repairs and downtime.
Why Lightning Surge and Voltage Protection Matters?
Surge arrestors are specifically designed to absorb and redirect these surges to the ground before they reach sensitive equipment, preventing permanent damage. Installing surge protection devices at key points in your system, like power lines, data cables, and control systems, helps ensure that these high-energy events don’t affect your critical infrastructure.
