- Why do I need to use a PowerGuard when I have a Filter?

- I understand the basics but how does the PowerGuard Protect?

- How does the Professional Series Filter Protect?

- What load can the spike arrester and filter support, can I plug a multiple outlet Power Board into the device?

- I have an Earth Leakage Circuit Breaker on my house, why do I need anything else to protect?

- The electrician who installed my ELCB has recommended and fitted a Surge Protector on the distribution board and says that’s all I need, but having read the info on your website there seems more to it, what should I be doing?

What are the differences between the PowerGuard (PG3701) and the Power Filters (CPF3500, CMP3901, and CMP3903)?
PowerGuard Original (PG3701) is a patent design, Voltage Limiting Device and Surge protector, and is specifically designed to monitor and limit voltage so that only voltage within a safe operating window between 190V AC Low - 265V AC High, flows through to the protected equipment. The PowerGuard protects by isolating the protected equipment from potentially damaging power.

The Power Filter range is a combination of a Spike Arrester and Power “Sifter”. The Power Filter protects by arresting and diverting potentially damaging high voltage spikes to earth and cleans (sifts or filters) the AC power of transient noise by capturing and dissipating the transient pulses through the filter circuitry to Earth.
