Feature: 1. Function and Installation: The DC isolation switch is used to turn off all poles of the solar module. It is installed on the string cable between the module and the grid inverter or charge controller. 2. Switching Current: The DC isolation switch can switch switching currents of up to 32A at voltages up to 1500V. Reasonable design, load breaking up to 8 times the rated current, suitable for motor isolation. 3. Flame Retardant PC Material: The DC disconnect switch is made of flame retardant PC material and IP66 waterproof case with good heat dissipation. Adopt magnetic arc extinguishing and arc extinguishing grid, effectively suppressing arc, high working safety. 4. Equipped with Password Lock: DC isolation switch can be locked by pulling out the pull bar when it is manually set back to close, which can be inserted and removed repeatedly for many times to prevent misoperation more safely and provide safe docking. 5. Wide Application: The isolation switch is widely used in RV, ship and grid connected solar system, off grid solar system, DC power system, ship power system, solar photovoltaic system or etc. of solar power system.
