They provide secure and reliable connections for electrical circuits, ensuring efficient current distribution and system stability. Constructed with high-quality materials, the CQMG03 series ensures excellent conductivity and durability, making it suitable for various industrial and commercial applications. The modular design allows for flexible installation and easy integration into existing electrical infrastructure, enhancing the overall efficiency and reliability of electrical distribution networks.

Overview and applications

CQMG03 series Connection boxes are suitable for 50 Hz AC rated current to 125A/160A distribution circuit, mainly used as buses and terminals in electrical equipment.

The CQMG03 series junction boxes are designed with superior conductivity and durability for a variety of environments. Carefully selected materials withstand the harsh power distribution environment, ensuring the junction boxes maintain their integrity and performance over time. A key feature of the CQMG03 junction box is its modular design, enabling flexible installation and easy integration into existing power infrastructure.

The CQMG03 series junction boxes are also designed to withstand high electrical stresses. Rated for a short-time withstand current of 4.5kA and a peak withstand current of 20kA, these junction boxes can handle short-circuit conditions without compromising safety or performance.

Industrial-grade design, compact with reliable insulation.
