Solar Panel DC Isolator Switch

描述

Solar DC isolator switches are suitable for isolating lines in high-voltage direct current transmission and distribution systems, such as cutting off high-voltage direct current between solar panels and inverters.
In the harsh working environment, it provides safe and reliable control of the power supply, high safety, and can be used with confidence.

Application:

Solar DC series isolator switch is suitable for a power system with rated voltage DC 1200v or below and rated current 32A or below.
The product can be used for infrequent switching-on and switching-off and can disconnect 1~2MPPT lines at thesame time. It is especially suitable for isolating lines in HVDC transmission and distribution systems, such ascutting off the high voltage direct current between solar panels and inverters.
