CITEL DLU Series – DIN Rail Surge Protection for LED Lighting and Control Systems
Type 2 SPD | 230 V AC | Compact DIN Rail Mount | Thermal Protection & Status Indicator
The CITEL DLU Series is a compact, high-performance Class II (Type 2) surge protection device engineered for LED lighting systems, control panels, and outdoor infrastructure networks. Designed for integration into lighting distribution cabinets or pole bases, the DLU Series delivers reliable protection against transient overvoltages caused by indirect lightning strikes and switching events.
With DIN rail mountability, integrated thermal disconnection, and visual status indication, the DLU Series is quick to install and maintain, making it ideal for both new projects and retrofits. Its compact design makes it a go-to solution for confined enclosures where robust protection is still essential.
