Product Description

Product Description

ONCCY  developed and launched the ERS series rapid shut down switch(RS switch). After installing the Onccy switch, firefighters can remotely turn off the AC power before extinguishing the fire. The quick-shutoff switch will automatically disconnect the internal DC isolation switch after collecting the signal from the power grid.
 

The 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 actual fire without the risk of electrocution. Onccy developed the Firefighter safety Switch according to this standard international safety routine. 
 

• AC power shut down =automatic DC power shut down
• Auto reset when AC power is back = DC power is back
• Easy to install for small to large, existing and new installations
• Based on the world's most used DC switch from ONCCY
