8579/8581 Series Plugs & Receptacles
Provide unique solutions for electrical connections in hazardous and corrosive environments
The 8579 and 8581 Series of plugs and switched receptacles provide unique solutions for electrical connections in hazardous and corrosive environments in the following industries:
• Chemical Pharmaceutical
• Petrochemical Offshore Energy
• Refining Coal Mining
They are made almost entirely from non-metallic material, and are available in 63A and 125A models.
This system makes the mating of plugs and receptacles of different voltages and current ratings physically impossible as required by the National Electrical Code. The plugs and switched receptacles are color coded according to voltage rating and ground pin position.
Each receptacle contains a horsepower rated disconnect switch. The circuit cannot be energized until the plug is inserted and the switch is turned to the ON position. The plug cannot be removed until the switch is turned to the OFF position, thus de-energizing the circuit.The switch handle is padlockable in the ON or OFF position.
The disconnect switch includes an auxiliary contact (late make, early break) as standard. This can be used for connection to a pilot light which can be used to signal power ON or power OFF, at a remote location.
