1 Control / Terminal Blocks Industrial & Hazardous Area Terminal Block General Technical Description Environmental Protection Productrelated Environmental Protection The health of our employees as well as the reduction of environmental impact through our products are in the focus of SAMWHAs accurate environmental management. RoHS The restriction of lead and five other potentially hazardous substances in electrical and electronic equipment is specified by the EUDirective 00//EC. The following substances used in electronic products are within the limits of the directive: Lead (Pb) of ppm Mercury (Hg) Cadmium (Cd) Hexavalent chrome (Cr (I)) Polybrominated biphenyl (PBB) Polybrominated diphenyl ehters (PBDE) Rating The Clearance and Creepage Distances of Electrical Equipment Clearance Distances Clearance distances are rated in accordance with the following factors : Anticipated overvoltages Used Measures to prevent soiling Creepage Distance Diagram showing clearance distance Clearance Distances Creepage distances are rated in accordance with the following factors : Intended Measures to prevent soiling Used insulation materials X Diagram showing creepage distance

3 Control / Terminal Blocks Industrial & Hazardous Area Terminal Block General Technical Description Insulation Material Group The insulation materials are divided into four groups depending on the comparative figures for creepage distance (CTI : comparative tracking index) : I II III a III b CTI 00CTI 175CTI00 0CTI175 The comparative tracking index is required to have been determined using special samples produced for this purpose with test solution A in compliance with IEC 011 Converting Conductors to This gives no indication of the actual conductor crosssectional area. The relationship between and is shown in the following table Materials Polyamide PA is one of the most frequently used technical plastics. The advantages of this material includes its very good electrical and mechanical properties, flexibility and resistance to breakage. In addition, its chemical structure gives PA good fire resistance even without the use of flame retardants. Polybutylene Terephthalate offers excellent dimensional stability and high continuous service temperature. It has lower creepage current resistance than other insulation materials. Steel parts whose function is to permanently maintain contact force are Zinc electroplated, with an additional chromate layer added to provide additional passivation. Surface protection complies with the very highest standards. Results from laboratory tests are incorporated in producing the surface finish. Zinc still offers corrosion protection over a longer period of time even if the Zinc coating is partially damaged by scratches or pores. Zinc acquires a negative charge in relation to steel under the influence of an electrolytic fluid. The metal ions in the Zinc migrate to the steel giving the base material lasting protection against corrosive attack. Conductive Materials The currentcarrying materials copper, brass and bronze are characterized by both high conductivity and good mechanical properties /0 /0 3/0 /

Both the tension clamp and the clamping screw consist of hardened steel. This clamping yoke unit generates the necessary contact force. Connection of the conductor involves the tension clamp pressing the conductor against the busbar, which is made of copper or high quality brass.
