Surge Protection Device (SPD)

The RY1-D series surge protection device, SPD for short, is suitable for use inearthing system, like TN-S, TN-C-S, TT, IT, etc., with the rated voltage up to 380V and the frequency of AC 50 or 60Hz. It is installed in the joint of LPZ1 or LPZ2 and LPZ3.

Designed according to IEC61643-1 and GB18802.1, this product is mounted on a 35mm standard rail. It is equipped with a disconnecting module. When the SPD fails in breakdown due to overcurrent-induced overheating, the disconnecting module is able to disconnect the SPD from the power grid and issue a visual alerting. Green light means normal and red indicates failure. This module can be replaced without cutting off the power supply.

Product Features
1. Our surge protection device can withstand the impact of 8/20μs 20kA lightning current.
2. Its action response time is less than 25ns.
3. The disconnecting module can be replaced without cutting off the power.
4. The color of the visible window indicates the operating status of the product, i.e., green represents normal and red means fault.
