Surge Protector

A surge protector is an electrical device designed to protect electrical equipment from voltage spikes and surges, which can be caused by lightning strikes, power outages, or other disruptions in the power supply. In Australia, surge protectors are crucial for safeguarding sensitive electronics and appliances from damage due to unexpected voltage increases.

Surge protectors work by diverting excess voltage away from connected devices and directing it safely to the ground. They typically include components such as metal oxide varistors (MOVs) or gas discharge tubes, which absorb and dissipate the surge energy. Surge protectors are rated based on their clamping voltage, which is the maximum voltage they allow through to the protected devices before activating, and their energy absorption capacity, which indicates how much surge energy they can handle before becoming ineffective.

In Australia, surge protectors must comply with standards such as AS/NZS 3760 for electrical safety and testing. These standards ensure that surge protectors perform reliably under Australian conditions. Surge protectors are commonly used in both residential and commercial settings, particularly for protecting valuable electronic equipment like computers, home entertainment systems, and office machinery. Regular inspection and replacement of surge protectors are recommended to ensure continued protection.
