Recently, the National Electric Light Source Quality Supervision and Inspection Center of Shanghai Quality Inspection Institute successfully passed the CB laboratory evaluation of the International Electrotechnical Commission's Electrical Product Qualification and Certification Organization (IECEE) in Shanghai, marking the first professional international CB of China's lighting industry. The global mutual recognition of electrical products) laboratory was born. The CB system is a truly global mutual recognition system for electrical products established by IECEE. It can directly issue 12 209 standard CB test certificates and is recognized by 53 countries and regions. Companies using CB test certificates obtained from certification bodies in any of the member states are exempt from repeat testing in other countries and are recognized by their member states. Successfully passed the CB laboratory review, so that the National Electric Light Source Quality Supervision and Inspection Center of Shanghai Quality Inspection Institute has the qualification to provide CB report for lighting electrical appliances exported to the world, and can provide CB certificate for Chinese lighting products, especially LED lighting products. Professional services have enabled China's lighting products to have access to the international market and play an important technical support role in improving the international competitiveness of Chinese companies and the overall strength of China's lighting industry.
With Push-in connection technology, you can connect conductors easily – both directly and without tools, insert forces reduced by 50%. it is suitable for various applications. Insert rigid conductors or conductors with ferrules from 0.25mm² into the conductor shaft.The contact spring opens automatically and provides the required pressure force against the current bar.
When installing smaller conductors from 0.14mm², use a standard screwdriver to push the orange button and actuate the contact spring.
Push-in Connection have test and passed various certificates. For example, Vibration resistance in accordance with railway standard DINEN50155,shock and corrosion resistance in accordance with current shipbuilding registers.
