Important

This device is not a lightning arrester and will not protect equipment against lightning strikes.

Hundreds of power surges can occur in your home or office every day. The switching on/off of fluorescent lights and household 
appliances like refrigerators, washing machines and tumble dryers can cause power surges. Most new product warranties do not 
cover power surge damage. These surges and spikes can seriously damage electronic equipment. Even low energy surges can 
cause gradual component degradation leading to early hardware failure. Surges can cause computers to crash and corrupt software 
and data.
SURGE TECHNICAL DATA EXPLANATION
• Maximum Surge Energy Joules Rating (J)
A Joule is a unit of energy absorbed by a surge protector. The higher the Joules rating, the better the protection.
• Maximum Surge Current (A)
The maximum non-repetitive surge that can be discharged by the surge protector. The higher the amperage, the better the 
protection.
• Clamping Voltage (V)
This is the voltage level at which the surge protector cuts off the power surge. The lower the clamping voltage, the better the 
protection.
• Three Channel Protection
Masterplug SurgeGuard products protect all three channels - i.e. between live and neutral (L-N), neutral and earth (N-E) and live and 
earth (L-E). Many surge protectors do not have three electrical circuits for maximum protection.
• Safety Thermal Cut-Out
• Surge ‘Neon’ Indicator
• Response Time (nS)
Repeated low surges over a period of years or one high surge can lead to the components in the surge protector degrading. This 
can lead to temperature rise and combustion. All Masterplug Surge Guard products have a safety thermal cut-out to protect against 
this eventuality. Don’t compromise on safety - insist on a safety thermal cut-out.
If the surge protector circuit fails, maybe as a result of discharging a maximum surge, you need to know so that the extension lead
can be replaced. Many surge protectors have no indicator so it’s impossible to tell if the connected equipment is actually protected!
Being protected is being aware.
All Masterplug Surge Protectors respond in less than 10 nano seconds (=10 thousand millionths of a second) - fast enough to 
protect your equipment.
