COOPER Crouse-Hinds has launched a new range of explosion-proof (Ex e) bus-bar systems for metal and moulded plastic enclosures. The system is suitable for use in hazardous environments with extreme ambient conditions. The GHG 758 bus-bar system utilises undrilled clamp technology for the connection of cabling, therefore enabling faster, more cost effective assembly and more efficient distribution of electrical energy. The system is designed to operate in ambient temperatures from –55 to +55ºC. It is available in high rated currents for 250A and 315A in Ex e certified technology for Zone 1 hazardous areas. The system can be used in conjunction with the company's modular range of GHG 619 enclosures and is a more cost effective solution for many Ex e IIC applications. In addition, the innovative design of the GHG 758 provides users with an increased length of us-able bus-bar rail of up to 6,300mm. An optional removable plastic cover is also available, which also provides additional cut-outs for measurements.
