LY1-B60 surge protective device(SPD) is suitable for 380V AC 50/60HZ TN-S, TN-C-S, TT, IT etc. power supply systems. It is normally installed on the joint of LPZ1 or LPZ2 and LPZ3, designed accordingly to IEC61643-1, GB18802.1 standard. It features standard 35mm din rail installation. There is a failure release mounted on the module of the surge protective device. When the SPD fails due to overheating or over-current, the failure release will help the electric device separate from the power supply system and give the indication signal (Green means normal, Red means fault).

• Module design: Easy to install, and replace the module without needing to power off.
• Inside protection: Equipped with over-current, over-heat, and temperature control open circuit protection.
• Fast response: Features fast response time and low residual voltage.
• Visual indication: Color window indicates working condition (green means normal, red means fault).
• High endurance: Maximum discharge current can endure 60KA (8/20µs).

LY1-B60 is Class B lightning protection degree, installed on the joint of LPZ0A or LPZ0B and LPZ1 zone, usually installed in low voltage main power distribution boxes connected to the incoming end of buildings.
