    These high quality electrical connection blocks allow efficient and easy wiring connections of ovens, infrared heaters, quartz tube heaters in furnaces, kilns, catering equipment, but also in equipment that must withstand fire whilst maintaining their function such as road and railway tunnels and military equipment

  • Elevated terminal plastic connection blocks

    In electrothermal connection applications, especially in immersion heater connection boxes appear specific constraints: high ambient temperature, frequent thermal cycles, and confined space around the ends of the heating elements and their terminals, making difficult to the user to make connections. These terminals have been developed to address these constraints.

  • Technical introduction of connection blocks made in ceramic and polyamide

    Ceramic was the first insulating material used in the electrical connection terminals. Mechanically resistant, exceptionally fire resistant, excellent electrical insulator, it had all the qualifications. Produced from locally available raw materials, ceramic and porcelain glazed electro-technical parts were essential in the beginnings of electricity until the appearance of Bakelite in the 1930s, then of engineered thermoplastics to 1960.
