Terminal Blocks With Current Carrying Capacity Far Exceeding International Standards
In the field of industrial electrical connections, the current carrying capacity of terminal blocks directly determines the stability and safety threshold of equipment operation. A groundbreaking industrial grade terminal block with a rated current of 232A and a wire adaptability of 95mm ², far exceeding the IEC 60947-7-1 international standard, has become the core choice for high-voltage scenarios such as railway industry and factory engineering.
Its performance breakthrough stems from core technological innovation: using a highly conductive copper alloy substrate and PowerTurn connection structure, the contact resistance is as low as 0.1m Ω, achieving stable transmission of 232A under a 95mm ² wire load, and increasing the current carrying capacity of conventional terminals by more than 40%. Paired with PA66 flame-retardant insulation shell (UL 94V-0 grade), the temperature resistance range covers -60 ℃ to 110 ℃. Even in harsh environments with pollution level 3, it can maintain insulation reliability at 1000V rated voltage and withstand surge voltage up to 8kV.
Modular design further expands the adaptation scenarios: supporting 25-95mm ² rigid and flexible wire connections, with a stripping length of only 40mm, and compatible with NS 35/15 standard rail installation, it can be flexibly integrated into equipment such as distribution cabinets and motor drivers. Double screw crimping technology enhances vibration resistance, reducing failure rates by 30% and extending maintenance cycles to 12 months in high-frequency vibration scenarios such as welding robots in automotive factories.
Through multiple international certifications such as UL, CE, ATEX, etc., this terminal not only meets the high-power requirements of industrial automation, new energy and other fields, but also achieves breakthroughs in key indicators such as explosion-proof and anti-corrosion, providing safety redundancy for high current transmission and becoming the core connection component for promoting industrial equipment upgrades.
