Model No: YSPD
YSPD Surge Protective Device
The YSPD Series surge protective device (SPD) is engineered to safeguard AC power systems with a 380V, 50/60Hz rated voltage. It provides comprehensive protection against various transient overvoltages, including those caused by direct or indirect lightning strikes. This versatile SPD is compatible with multiple power system configurations, such as IT, TT, TN-C, TN-S, and TN-C-S. It's a Class I (Type B) device, certified to meet both the IEC 61643-1:1998-02 and GB 18802.1 / IEC 61643-1 standards. The YSPD series offers both common mode (MC) and differential mode (MD) protection, ensuring robust defense for your electrical systems.

YSPD Series Surge Protective Device: A Comprehensive Safety Solution
A key element of this device's safety system is the Thermal Disconnector. Every YSPD unit incorporates a Thermal Disconnector, and this Thermal Disconnector is a critical safety feature. The Thermal Disconnector is designed to prevent a fire. When the SPD’s internal components are subjected to a powerful, sustained surge or a series of surges, they can overheat. The Thermal Disconnector senses this excessive heat. Once triggered, the Thermal Disconnector automatically disconnects the SPD from the power circuit. This action by the Thermal Disconnector prevents thermal runaway and protects the entire electrical system. The state of this Thermal Disconnector is indicated by a visual window: a green window means the Thermal Disconnector is functioning normally, while a red window indicates that the Thermal Disconnector has activated and the device needs to be replaced. This visual feedback, directly tied to the Thermal Disconnector, ensures that the status is always clear. Without the Thermal Disconnector, a failed SPD could pose a serious risk.
The device's powerful performance is defined by its impressive Maximum Discharge Current rated at up to 100kA per line. This high Maximum Discharge Current is what enables the YSPD to handle direct lightning strikes effectively. The Maximum Discharge Current rating is a critical measure of an SPD’s capacity. A high Maximum Discharge Current ensures that the device can safely divert a massive amount of energy to the ground. This high Maximum Discharge Current is a primary reason why this device is chosen for critical installations. The ability to handle a high Maximum Discharge Current is a testament to its robust design. The Maximum Discharge Current is the main line of defense against powerful surges. When a surge event occurs, the device's Maximum Discharge Current rating determines its ability to cope with the energy. This impressive Maximum Discharge Current capability is a hallmark of a high-quality Class I SPD. The installation must also be done correctly to fully utilize the Maximum Discharge Current. A short grounding wire is essential to ensure the Maximum Discharge Current can be safely dissipated.
Proper installation is non-negotiable for maximizing the benefits of the Thermal Disconnector and the high Maximum Discharge Current. The YSPD must be correctly placed within the overall Lightning Protection Zone (LPZ) strategy. The correct Lightning Protection Zone for this device is the boundary between Lightning Protection Zone 0A/0B and Lightning Protection Zone 1. This specific Lightning Protection Zone is where the SPD can intercept lightning currents before they enter the internal wiring. The concept of the Lightning Protection Zone helps to guide the placement of all SPD devices. By installing the YSPD at this key Lightning Protection Zone, you are implementing the first line of defense. The entire Lightning Protection Zone system relies on this device being in the right place. A misplaced SPD, even with its high Maximum Discharge Current and reliable Thermal Disconnector, will not provide adequate protection. Therefore, always follow the Lightning Protection Zone guidelines. The YSPD is a fundamental part of any comprehensive Lightning Protection Zone system. This device is the critical link in a multi-level Lightning Protection Zone defense strategy.
