●DC Power Isolation Switch
●For photovoltaic system protection
●PC material V-0 flame retardant insulation
●Waterproof dustproof and impact resistant
●Cut off the voltage direct current to the solar panel.
YRDS1 series 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.
YRDS1 series isolator switch is suitable for a power system with rated voltage DC 1200v or belowand 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.
lnstalled at any angle can achieve lP66waterproof level
