Terminal’s elements Insulation part The material of the insulating body of the terminals type VS PA is PA 6.6 polyamide (self–exstinguishable - colour of ebony acc. to RAL 1014) which is made of polyamide resin and has higher temperature resistance, it is thermal stabilized and is resistant to aging. Polyamide 6.6 has good geometrical stability and excellent mechanical resistance. The material satisfies regulation according to IEC 695-2-1. It is suitable for use in temperature range from -40º C to +100º C according to IEC 216 rules. In the mentioned range the material remains unchanged. It is resistant to oils, greases, salts, several alkaline solutions ant to low percentage of acid concentration. It is resistant to micro-organisms, bacteria, fungi, enzymes and termites. The design of the insulation body of the terminal consider the regulations of air and creepage distances of nominal voltage according IEC 947-1. Terminal body The terminal body of 2,5 mm2 connecting elements are made from brass, others are made from steel. The body is equipped with a hole with thread for obtaining screw pressure. In the final phase of the production the bodies of brass are treated by coating with Ni and other are treated by coating with 12 microns of zinc and with blue pasivation. In this way galvanically and corrosion protection is obtained. The terminal body has excellent mechanical characteristics and they are not subject to mechanical deformation in ordinary use, which are prescribed with IEC 947-1 regulations. Terminal bodies are equipped with body nose (except terminal body VS 2.5 PA). So, it is avoided to insert cable under body if the terminal body is closed or half closed.
