Human Life & Home Protection Device (Protector) Boris Fradkin 2015 A.L.F. Enterprise

Protector Description  The Protector is a small and effective electronic protection device that can be implemented in every electrical installation and in every electrical appliance.  The device allows to raise drastically both the level of human protection against electrocution and the level of protection against home fires.

The Problem US Consumer Product Safety Commission determined in its publication from 2004 that problems in home wiring are associated with more than 40,000 home fires every year. These fires claim over 350 lives and endure 1,400 victims annually. The reasons for the fires are: - defective plugs and sockets - defective home electrical appliances - overvoltage, overcurrent, undervoltage

The Problem (cont.) Electrocution is the result of: Defective home electrical appliances without grounding or with defective grounding Inserting metallic parts into sockets by children Protection restrictions of Residual Current Devices (RCD):  Only leakage protection  10% of RCDs do not operate properly  High current threshold – 30 mA  RCDs do not operate without grounding

The Problem (cont.) The existing overvoltage protection device has the following disadvantages: Does not operate without grounding. Is sensitive up to 12 V between zero and grounding. Is very expensive. Disconnects all the home appliances from the mains. As a result, the device is not in use.

The Solution The Protector – a small electronic device for current and voltage control that disconnects from the mains a specific electrical installation or a specific electrical appliance when there are dangerous deviations from the nominal current and voltage parameters. The Protector shall be implemented: Into sockets Into plugs Into adapters Into electrical appliances at the mains input

The Protector Has Many Types of Protection Leakage protection AC or DC shock protection Overvoltage protection Undervoltage protection Overcurrent protection Fire protection Arc protection Zero absence protection Live and zero feeders change protection “Children” protection

First Implementation Electrical sockets in Israel, first customer – Waisbord Ltd. Additional production cost to the existing sockets is about $3 Marketing potential for Israeli sockets is more than US$48M annually World marketing potential is more than US$7,2B Time to market: 8-12 months Feasibility of the protector was proved in the inventor’s laboratory

Technology This unique protection device is based on ultra high sensitive and fast detection and response to dangerous currents and voltages The idea and the methods belong to the Inventor, Mr. Boris Fradkin A patent search was performed, no such technology is available There are technological entry barriers for developing and manufacturing a product similar to the Protector

Business Development Standardization: Certification in every country from standard institutes. There are 13 different types of sockets in the world. Every type needs the Protector adaptation. Contacts with electrical appliances producers for integrating the Protector in their devices. New markets development.

Road Map Development of sockets with the Protector for the European market Development of sockets with the Protector for the Israeli and American markets Development of additional devices – line of protection devices based on the Protector Cooperation with electrical appliances producers
