Application:
The product is a multi-port signal surge protective device engineered for high-density network protection with Power over Ethernet (PoE) support. It is specifically designed for installation at network switches, IP device endpoints, and communication cabinets in LPZ 2 to LPZ 3 zones (commonly referred to as Type 3 or Class D protection). It effectively safeguards sensitive network equipment such as IP cameras, wireless access points, and VoIP phones against damage from induced transient overvoltages on both data lines and PoE power lines.
