    The JCH2-125 Main Switch Isolator is a versatile and reliable device designed to efficiently use the main switch while cutting off the connection between live and neutral wires. This makes it suitable for a wide range of applications, including residential, light commercial and industrial environments.  The JCH2-125 main switch isolator is available in rated currents of 40A, 63A, 80A, 100A and 125A, providing flexibility to meet various power requirements. It is available in 1-pole, 2-pole, 3-pole and 4-pole configurations with a rated frequency of 50/60Hz and a rated impulse withstand voltage of 4000V, ensuring reliable operation in a variety of electrical systems.
    The JCH2-125 isolator has a green/red indicator on the handle that provides positive contact indication through a visible window indicating a 4mm contact gap. It is 35mm DIN rail mounted, easy to install and compatible with pin/fork standard busbars, making it ideal for applications requiring localized isolation. It is worth noting that the JCH2-125 isolator is only a main switch and does not include overload protection. It is designed to cut off the load circuit and may trip if a sub-circuit fails, functioning both as a main switch and as circuit protection.
    In addition, the JCH2-125 main switch isolator complies with IEC60947-3 and EN60947-3 standards, ensuring it meets international standards for safety and performance, giving users and installers peace of mind.
