800VDC T2-class surge protector: providing advanced protection for high-voltage DC systems

The device's three-pole configuration provides comprehensive protection for the positive, negative, and ground conductors in DC systems, ensuring complete protection against surge events. Its T2 rating meets international standards for handling indirect lightning strikes and switching surges, making it suitable for a wide range of applications. Its 800VDC voltage rating makes it an ideal solution for high-voltage applications in renewable energy systems and industrial environments. A standard discharge current of 20kA ensures consistent performance under normal operating conditions, while a maximum capacity of 40kA provides robust protection against severe electrical transients.

An integrated thermal protection system automatically disconnects the device in the event of overload or end-of-life, enhancing safety. Clear visual status indicators allow for quick assessment of device status, while the DIN rail mount design facilitates easy installation within standard electrical cabinets. Screw terminal connections ensure secure wiring, contributing to long-term device reliability. The red plastic housing provides excellent electrical insulation while being clearly visible and easily identified within switchboards.

This surge protector is primarily used in large-scale photovoltaic systems to protect solar inverters, combiner boxes, and monitoring equipment from lightning surges. Industrial applications include protecting high-voltage motor drives, programmable logic controllers (PLCs), and automation systems in manufacturing environments. The device is also effective in applications requiring high-voltage DC protection, such as electric vehicle charging infrastructure, telecommunications power systems, and data center backup power.

Other applications include railway electrification systems, mining equipment power supplies, and marine electrical systems. The device is suitable for both indoor and outdoor sheltered installations, offering flexibility in various environmental conditions. Building management systems and security systems also benefit from the reliable surge protection it provides, ensuring the continued operation of critical systems.
