Product Details

Switch-type I grade AC surge protector FD11-440/50B-3P
 
FD11-440/50B-3P, mainly used in the class 1 lightning protection for low-voltage power supply and distribution systems. It is designed for electrical equipment protection and to discharge, suppress and reduce operational overvoltage caused by lightning strikes or the power grid system. With large impulse discharge current, low camping voltage, no arc leakage and strong interrupting freewheeling current, it is suitable for TN-C grid system.
 
Installation Fig.

Features

  • Module design, easy to install, and change change module no need power off.
  • Inside over-current, over-heat, temperature control open circuit.
  • Fast response time, low residual voltage.
  • Window color indicates working condition, green means normal, red means fault.
  • Max discharge current can endure 40KA(8/20). Installation position On the joint of LPZ1 or LPZ2 and LPZ3 usually installed in household distribution boards, computer equipment,information equipment,electronic equipment and in the socket box in front of control equipment or near the control equipment.
Application

 

    MYS5 385V AC 1P+N-PE surge protective device(SPD) is suitable for 380V AC 50/60HZ TN-S, TN-C-S, TT, IT etc. Power supply system. Normally installed on the joint of LPZ1 or LPZ2 and LPZ3, designed accordingly to IEC61643-1, GB18802.1 standard. It's standard 35mm din rail installation. There is failure release mounted on the module of surge protective device. When SPD fails in breakdown for over-heat or over-current, the failure release will help electric device separate from the power supply system and give the indication signal. Green means normal, red means fault.
