Enclosure-less Surge Protection Deivce

Enclosure-less Panel Surge Protection Device – for Local Made / SKD

UL1449 5th listed Prosurge’s PCB Assembly (PCBA) series are one-stop high performance surge protection solution for worldwide OEM customers. They are fully functional and flexible surge protection PCB assembly and thus will significantly reduce customer’s investment in designing, certifying and manufacturing and thus ensure an efficient local-make product at minimum cost.

PCBA series fully meet the demanding protection requirements of equipment operation in high-risk or critical commercial and industrial environments. By employing Prosurge’s patented technology, a thermally protected and arc extinguishing MOV technology (PTMOV/20PTMOV/SMTMOV/HSMTMOV), PCBA series have a significant advantage in abnormal over-voltage & high fault current safety to deliver industry’s highest level of safety and performance. The parallel redundancy modules design makes the PCBA more robust and reliable and ensures that they can handle great impulse current up to 900kA and multiple impulse current at its highest rated level.


Prosurge will handle the complicated and time-consuming jobs in manufacturing a panel type surge protection device so that customers can maufactuer their UL listed panel type SPD at mimum cost and time.
