DIN Rail 2 Pole Surge Protector With NO NC Remote Signalling, Single Phase Secondary Remote Monitoring Lightning Module
About this item
2-pole single-phase Type2 surge protector integrated with NO/NC dual remote signalling contacts, solving maintenance challenges of unattended small single-phase cabinets where module degradation cannot be alerted timely without frequent manual inspection. Passive dry contacts switch alarm signals automatically when thermal disconnection occurs due to overheating aging; signals transmit to PLC, SCADA and building BA systems without auxiliary power supply. Front green-red visual window provides instant on-site status verification. The unit delivers 20kA nominal and 40kA maximum discharge current, multiple Uc grades from 275Vac to 440Vac, ≤25ns fast surge clamping. Plug-in modular design fits standard 35mm DIN rail, PA6 V0 flame retardant housing operates steadily from -40℃ to +70℃ indoors, ideal for remote LPS monitoring of retail stores, small factories, residential solar and EV charger single-phase sub-distribution systems.
