YCRS Rapid Shutdown Device

General
The YCRS series rapid shutdown device can shutdown 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.

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.
