A double pole DC contactor is a high-performance electrical switching device used to control and protect DC circuits. It features two sets of main contacts that can switch and carry high currents up to 1,000 volts per contact system. The contactor is designed for frequent switching under load and can disconnect currents up to 120A with 1,500V. It employs permanent magnets and arcing chambers to safely extinguish switching arcs. Double pole DC contactors are compact, reliable, and suitable for use in extreme temperatures from -40°C to +70°C. They are commonly used in applications such as battery systems, photovoltaic inverters, and UPS systems
