"Electric Leakage protection wal" precise formulation should be "water resistance isolated attenuation protection way".

The general impression is that the water is a conductor and the electrical contact is very dangerous. In fact, any objects are all resistance, in line with the premise of the economy it could be transformed apparatus into the needs of the people.

"Electric Leakage protection wall" uses the water itself resistance (GB provides water resistance at 15 C greater than the rate of 1300?. Cm), through choosing the material of the water heater pipes (insulating material), diameter and distance to form an" Electric Leakage protection". When the water heater is working, even though there is electricity in the chamber water, the electricity will be isolated and attenuated by "Electric Leakage protection wall " to get isolate the electricity purpose. This way could achieve the purpose of access to water heaters at both ends to almost zero voltage and a very weak current below 0.02mA/kw.

The "Electric Leakage protection wall"technology not only isolating the water heater itself leakage, and can also block security threat from earth wire leakage or shower water pipes leakage. So an "Electric Leakage protection wall"can fully guarantee the security of Bath.

Our 5SM residual current operated circuit breaker with integral over current protection can be used in the domestic and public fields for optimum protection of life against the risks if in direct contacts and electrical installations against short-circuits or overload. The residual current operated circuit breakers with integral over current. Protection combines in fact a protection against ear thing faults (differential protection) and a protection against over currents detected in the installations magnetothermic protection versions suing a rated residual fault current of 30mA also assure an additional protection in case of direct contacts. KM series are equipped with over current triggers integrated and manufactured according to the most recent national and international regulations: standards IEC1009-1 and IEC2318, their sizes are in compliance with the regulations of the standard DIN43880, one module is 18mm (1pole), front window height equal to 45mm. According to IEC1009-1, FSM type of RCBO has no special operating process, so it can be sued by laypeople.

Recorder Nullifier is device that prevents any un-authorized recording of conversations with audio cassette recorders. The main funcation of RH-RJ101A is to jam the Audio Cassette Recorder and some Audio Digital Recorders. Jammer suppresses the operation of the recorders by radiating noise interference. The parameters of the noise interference are specially applied on the suppression of many types of recorders.

You can use jammer as desktop device in your office, as standalone device in your briefcase. It is in clock design and disguise its actual function. You can put any of the office items on top of it (such as phone set, penholder, etc. ). Thus, you can hide functioning of the jammer from anyone who is trying to get the confidential information.

You can use the remote control unit to activate/deactivate the suppression.

Furthermore the Recorder Nullifier RH-RJ101A can jamm 85% types of (Cassette Tape Recorder) analog recorder equiped with wire or without wire microphone that you can buy in the market and 55% types of digital recorder that you can fined in the market, but except digital recorder that integrated with mobile phone.

In addition, for your studying, we would like to remind you that our Recorder Nullifier is designed for individual user. For example, when you have the meeting at coffee with your client, you can put the jammer under the table and your conversation can't be recorded. The power of our jammer is 5 watt.

If you 'd like to use the jammer in the conference, you can buy two or three jammers and put them on the desk, that will work more effectively. The bigger size the jammer has, the more effectively the jammer can cut off the messages from others. Because it has stronger power. And that is our next product.

For the maximum and best jamming effect, the suppressing direction is at the right side of the jammer, and the suppressing distance is up to 8 meters for cassette recorder and 1-2. 5 meter for digital recorder suppresing beam width is 110 degrees horizontal and 110 degrees vertical. The jammer works by transmitting radio frequency, so it should be kept away from objects made of metal.

We supply Fuse Cutout up to 36kV with 100 and 200A. Most Cmpetitive price offered.
