This DC contactor is widely used in new energy vehicles, charging equipment, photovoltaic/wind power generation, energy storage equipment, cloud servers, high-speed rail, rail transportation,ships, aviation, robotics, industrial automation, etc.

This DC contactor (hereinafter referred to as contactor) is suitable for DC power supply, connection and breaking of DC power controller in the main circuit with the rated voltage of DC 750V and the rated current of DC 50A or less.
The arc extinguishing chamber cavity adopts vacuum brazed ceramic sealing technology, which has the characteristics of high voltage, high current, double insulation, small size and strong arc extinguishing ability, so as to ensure that the product does not catch fire or explode under proper use;
The main contacts are made of special copper alloy material,with strong breaking capacity, anti-adhesion and long life.
The arc extinguishing chamber cavity is filled with a certain pressure of inert gas mixture, which can effectively protect the main contacts, preventing them from oxidation and making them break more quickly.
The product has a built-in control coil energy saving device,which can reduce the energy consumption.
The overall protection level of the contactor can reach IP67 level.
The product implements GB/T 14048.4-2020 standard.
The product complies with IEC60947-4-1:2009 standard.
The product complies with EU RoHS requirements.
