The Phoenix Contact 2800187 AC surge arrester type 1+2 is a universal plug-in device designed to protect electrical systems from lightning strikes and power surges. It is suitable for 1-phase mains with separate neutral and protective earth conductors, employing a 3-wire system configuration (L1, N, PE). The unit is based on varistor technology, which ensures effective surge protection for sensitive equipment.

Featuring a secure plug holder, the arrester is capable of withstanding high surge current loads and strong vibrations, making it suitable for environments where stability and durability are essential. The modern latching mechanism contributes to the robustness of the connection, ensuring that the protective device remains securely in place even under demanding conditions.

Each individual connector within the arrester is equipped with a thermal separation device. This safety feature provides an additional layer of protection by isolating connectors in the event of overheating, thereby preventing damage to the electrical system and connected devices.

Mechanical coding of all plug connectors ensures correct installation and prevents mismating, which can lead to system failures or malfunctions. The product's item number is 4046356518581, and it is part of the PROTECTION VAL-MS-T1/T2 335/12.5/1+1 series from Phoenix Contact, a brand known for its commitment to quality and innovation in electrical components.
