Finder's 66 series of PCB power relays are designed to suit photovoltaic (PV) inverters, domestic appliances and other equipment needing reinforced insulation, high ambient temperature and full disconnection contacts. The 66 series of PCB power relays are rated up to 30A and available in DPST-NO or DPDT formats with AC or DC coils.
The DPST-NO versions (stock numbers 749-5133, 749-5137, 749-5146, 749-5143 and 749-5149) have a contact gap separation of 1.5mm, fully meeting the requirements of the VDE 0126-1-1 standard for photovoltaic (PV) inverter applications. In addition, stock number 749-5143 features a 5mm air gap (stand-off) between relay base and PCB for extra cooling, ideal in systems where forced air cooling is employed as with many photovoltaic (PV) inverters.
All of Finder's 66 series PCB power relays have been designed with an 8mm clearance and creepage distance, ensuring safe separation of supply and output, and reinforced insulation between coil and contacts, meeting the requirements of EN60335-1 (VDE 0700).
