PV Array Level Rapid Shutdown Switch 13A 20A 25A Safety Switch

Firefighter Safety Switch FactoryIn most photovoltaic systems, the dc isolator is integrated into the dc/ac power inverter. After switching off the dc isolator, the cables between the dc solar modules and dc/ac power inverter running through the building are still subject to up to 1000 v dc. in the event of a fire, firefighters are exposed to a very serious source of potential danger. The ONCCY firefighter safety switch provides the solution. It directly disconnects the dc current in close proximity to the solar modules and creates a safer situation for firefighters.MANUAL AC POWER SHUT DOWNThe first step for any firefighter in fighting a fire is to shut down the main AC power circuit. This makes it possible to start extinguishing the actualfire without the risk of electrocution. Onccy developed the Firefighter safety Switch according to this standard international safety routine. This prevents firefighters from having to take any extra action in case of a fire, maximizing their and your safety in the event of a fire.AUTOMATIC DC POWER SHUT DOWNAs soon as a firefighter shuts down the main AC circuit, the ERS/ERP will detect this. If this power down situation lasts longer than 5 seconds, theERS/ERP will automatically switch to the OFF position. Since the ERS/ERP is located close to the PV modules, the high voltage DC current from the PV modules will be completely isolated, which leaves a safe situation for the firefighters when fighting a fire in the commercial or residential building.AC power shut down =automatic DC power shut downAuto reset when AC power is back = DC power is backEasy to install for small to large, existing and new installationsBased on the world's most used DC switch from ONCCYPV Array Level Rapid Shutdown 6-8 stringsSuitable for 3-string,4-string,5-string modulesMaximum circuit current 55AMaximum cricuit voltage 1500vdcCE certificatedSheet metal material, IP66 protection gradeMulti clock interface type optional (knockout hole / gland / MC4 terminal)The Isolation switches are TUV.CE.CB.SAA certificated Company information FAQQ: Are you trading company or manufacturer ?A: We are manufacturer. We have 30,000 square meters of self-owned plant.Q: Do you have any certificates?A: Yes,we have UL, TUV, CB, SAA, CCC, CE and other certifications.Q: How do we make a quick response to customer , 5 inquiry ?A: Our professional team will reply you online or by email,Skype, whatsApp and so on.Q: Do you have any exporting experience?Which countries did you export to before?A: We have lots of exporting experience and customers in many countries,such as America, Japan,Australia,UAE,Canada,Vietnam,Turkey,Thailand,Russia,UK,etc.Q:Can you supply samples for checking ?A: Yes, we can supply samples, pls contact for detailed required.Q:How long is your delivery time?A: Generally it is within 3days for small qty.
