Main Features

  • Data network security in accordance with the standard 
  • IEEE802.3at/af,UL497b,IEC61643-21 
  • Ethernet system protection that is PoE-compatible 
  • High discharge capability with a total nominal discharge current of 10kA 8/20 and a lightning current of up to 1.0kA. 
  • The EMI Shielded Enclosure, 19″ bay design, can be easily installed on a standard 19-inch machine cabinet. 
  • With GDT and TVS technology, two-stage protection circuit limits transients. 
  • A PTC for over-current and short-circuit fault protection is included. 
  • RJ45 connector with 8 wires of protection for 100/1000 BaseT/BaseTX, ATM, and Token Ring network technology. 


The network SPD surge protection device, also called ethernet cable surge protector, protects a data line, including computer network signals, communication devices, and so on. Plug the ethernet port electrical surge protection devices into the data cable and ground it to prevent lightning surges from damaging the device. The APSDSB48/RJ45-1000-24P multiport Ethernet-PoEProtector is intended for use in category locations B and C (ANSI/IEEE C62.41) or directly upstream near the protected devices.
