“Cables, plugs, sockets and fittings must be robust enough and adequately protected for the working environment. Ensure that machinery has an accessible switch or isolator to cut off the power quickly in an emergency.”
This article explains the inherent dangers of working on or near electrical equipment under load and provides accident risk reduction advice for plant managers and safety supervisors who control the specification, selection, installation and operation of electrical equipment.
Effective safety measures can be introduced to counteract occupational electrocution, today we consider the seemingly benign plug. But firstly, the ever-present danger.
Fatal electrical injuries are inflicted irrespective of voltage or current. FACT. 50 volts of electrical current applied between two parts of the human body causes a current to flow that can block the electrical signals between the brain and the muscles, some effects include:
During electrocution the electrical current is conducted through the victims body heating tissue along the length of the current flow. Deep skin and flesh burns often require major surgery and can be permanently disabling. Loss of muscle function prevents the electric shock victim from “letting go” – personally helpless and ensnared.
Marechal, a world leading manufacturer of Electrical Safety Plugs & Sockets have innovated self-ejecting plugs and power connector systems designed to protect people and plant from electrocution caused by accidental or intentional disconnection of power supply.
Self-ejecting plug-socket systems eliminate the need to disconnect electrical equipment, allowing a mobile device to be moved while electrically connected without unplugging it, or where equipment is located in high-risk or hazardous area locations.
Marechal Self Ejecting Plugs. B = box, Sl = sleeve, S = socket outlet, I = inlet, Me = mechanism, H = handle and C = cord.
Whether you require a high IP rated electrical connector to permit washing down with a high pressure hose in the food and beverage industry, ATEX certified plugs for hazardous areas or up to 37 pin plugs for complex configured power and control distribution, we’re here to help. We support safe electrical circuits across all industries:
Self-ejecting plugs are available in the following Marechal Decontactor ranges:
Marechal DSN (DSN1, DSN3, DSN6) – AC-22 & AC-23. IP66/IP67/IP69k Water & Dust Tight
Marechal DN (DN1, DN3, DN3, DN6, DN8) – AC-22. IP54/IP55 Water & Dust Tight
Marechal DS (DS1, DS3, DS6) –Â IP54/ IP55. AC-22 / AC-23. Safety Shutter (IP4X/IPXXD Socket-Outlet)
Marechal DS7C3 – Star Delta Motor Connectors 50 Amps 500 Volts
Marechal DXN Decontactors certified according to ATEX ensure safe electrical power installations in hazardous areas – the explosion-proof range of compact and watertight plug and socket connectors feature a mechanical self-ejecting mechanism with Marechals unique patented Decontactor integrated load-break switch.
Marechal DXN decontactors are available in 3 different versions: standard plugs and connectors, self-ejecting plugs and self-ejecting coupler sockets.
The self-ejection plug-socket system for Zones 1/2 (gas) and Zones 21/22 (dust) is certified according to the ATEX 2014/34/EU directive and IEC Ex standards. Whether connected or disconnected, self-ejecting Marechal DXN decontactors can be operated by any authorised person under any circumstances.
