The YCS6-D 3P is a compact and reliable surge protection device (SPD) engineered to protect three-phase electrical systems from transient overvoltages caused by lightning strikes or switching operations. Operating at AC 385V, it features a 3-pole configuration and can discharge surge currents between 5kA and 10kA, making it suitable for TT, TN, and IT systems.
Its 36mm width allows for space-saving installation in distribution boards, and the yellow indicator provides clear visual feedback on protection status. Built to comply with IEC 61643-1, the device is typically installed at the incoming line of low-voltage distribution boxes.
The SPD supports DIN rail mounting (35mm) and operates reliably across a wide temperature range (–40°C to +85°C). It is recommended to pair with 10A–25A fuses or circuit breakers for optimal performance.
