Aswich ERP Series Solar PV Module Level Firefighter Safety Switch Rapid Shutdown

Rooftop type resident photovoltaic systems have been widely used globally. However, due to loose contact of photovoltaic module joints, poor contact, wire dampness, or insulation rupture, DC arc drawing can occur, potentially resulting in fire. In such events, the DC side continues to generate high voltage as long as there is light. This makes firefighting extremely dangerous, as firefighters often cannot approach the scene and must control the fire from a distance.

The ERP Series Panel Level Firefighter Safety Switches / Rapid Shutdown (PLC) provides a reliable rapid shutdown solution according to NEC 2017/2020 690.12 regulations for rooftop PV systems fire safety.
