Surge Protection Device (SPD)

Transient overvoltages pose a significant threat to modern electrical infrastructure, leading to equipment failure, data corruption, and costly downtime. Our range of Surge Protection Devices (SPDs) offers a robust defense, designed to quickly detect and safely discharge these harmful voltage spikes. Engineered for reliability and performance, these devices are crucial for maintaining the integrity and longevity of your electrical installations.

Our SPDs adhere to the IEC61643-11 standard, ensuring consistent performance and safety. They are suitable for a wide array of applications, featuring configurations for both AC and DC systems. Key specifications include a Rated Working Voltage (Ue) of 220V and a Maximum Continuous Operating Voltage (Uc) of 320VAC, providing ample protection margins. With a Nominal Discharge Current (In) of 20KA and a Maximum Discharge Current (Imax) of 40KA, these devices are built to handle significant surge events. The Voltage Protection Level (Up) of 1.7KV ensures that sensitive equipment remains protected, while a Rated Short-Circuit Current (Isccr) of 300A demonstrates their robust design. Our modular SPDs are easy to install on DIN rails, making them a practical choice for new installations and system upgrades, offering peace of mind against electrical transients.
