Product DescriptionGeneralThe YCRS series rapid shutdown device can
shut down one or two string modules at maximum, with a
maximum circuit current of 55A and a maximum circuit voltage of
1500VDC.It is made of PC+ABS material and has an IP66 protection
rating. Multiple interface types are available, including
push-through holes, pressure covers,and MC4 terminals.The internal
isolation switch is certified by TUV.CE.CB.SAA,and the device is
equipped with a waterproof and ventilated valve design to prevent
condesation inside the housing.An advanced temperature sensor is
used to detect the highest temperature inside the housing in
real-time, and the switch will automatically cut off when the
internal temperature exceeds 70 degrees Celsius. This device is
suitable for residential, industrial,and commercial photovoltaic
systems. Certification: CE Cause Why do photovoltaic power
generation systems need to be equipped with fast shutdown
devices.The use of rapid shutdown devices in photovoltaic (PV)
systems has become increasingly important due YCRS Rapid Shutdown
Device YCRS Rapid Shutdown Deviceto concerns about safety in recent
years.PV system accidents often result in fires, and 80% of these
fires are caused by DC voltage arcing. Additionally, because many
distributed PV systems are installed in densely populated areas or
near industrial facilities, any accidents or failures can lead to
significant losses of life and property.Therefore, many countries
require that PV systems be equipped with component-level rapid
shutdown devices in order to eliminate DC voltage in emergency
situations and protect the safety of firefighting and maintenance
personnel, as well as to ensure the overall safety of the system.In
the event of a fire or other emergency, maintenance personnel can
quickly disconnect each component by closing the YCRS device and
eliminating the DC voltage, thus protecting the safety of
firefighting and maintenance personnel.
