Double-Break Switch & Copper Bar
The Huntkey SZN507 comes with a double-break switch, which has breaks the electrical contact at two points, instead of a single contact. This not only offers twice the breaking capacity, it also provides a greater contact surface when the circuit is closed – allowing for better heat dissipation and a longer switch life.
Huntkey also plated the switch contacts with a silver-nickel alloy to reduce contact resistance, and protect them against corrosion and oxidation. Hence, the double-break switch is rated to last over 10,000 times.
To ensure maximum safety and lifespan, Huntkey used a solid copper bar internally to conduct electricity to the power sockets. As copper is a better conductor of both electricity and heat than aluminium or steel, the use of a copper bar would result in both a lower heat output as well as better dissipation of the heat.
The Huntkey SZN507 comes with a 3 meter (10 feet) long power cord. The length is important for many users, but many people ignore the quality of the cable – specifically the ability of the wires inside to conduct that much electricity. If the power cord does not use the proper wires, they will overheat and potentially start a fire.
The SZN507 use three insulated wires with a minimum conductor cross section of 0.75 mm². The power cord is therefore capable of handling a maximum current load of 12 A, or a maximum power output of 2,880 watts. In other words, the Huntkey SZN507 is more than capable of handling the rated power output of 2,500 watts.
Huntkey offers four different plug options for the SZN507, depending on which region it’s sold. Irrespective of the plug type the SZN507 comes with, the power plug is only fused for a maximum current of 10 A. And we checked – it actually uses a 10 A fuse. This is important because it guarantees that the SZN507 power strip is never overloaded.
Most power strips use the more common 13 A fuse. In most cases, you won’t face any issues, but there is a risk of overloading the power strip. Using a 13 A fuse would allow the power strip to receive up to 13 A of current, which would overload the (12 A) conduction capacity of the power cord, causing it to overheat and potentially melt and/or catch fire.
Our Verdict[adrotate banner=”4″]The Huntkey SZN507 is a power strip designed for the discerning modern family. Superficially, it looks just like any other power strip, but inside – it conceals a ton of safety features. Everything, from its internal copper bar structure to its 10 A fused plug, is designed to ensure that the SZN507 will never exceed its specifications and overheat or worse, catch fire.
We are not talking just about its listed safety features or its certification by various safety authorities. It is also about their attention to detail. Everything we inspected checked out, meeting or exceeding their own specifications. That is not something we can be sure of if we purchase an ordinary power strip from Walmart or Tesco.
The Huntkey SZN507 isn’t a power strip designed just for the techie who wants to ensure that his/her devices will never get destroyed by a power surge. Anyone who wants a properly-designed and built power strip for peace of mind should consider the Huntkey SZN507.
