  • Outline drawings

They render high surge protection for all lighting technologies. They are quite up to that task for the Class I luminaries.


This device is an economical single-phase surge protection gizmo especially designed for outdoor lighting. The security reception of L to N, L to Ground makes it quite efficient in its operation.

These compact devices are per international and national standards IEEE C62.41. It is connected parallel in a circuitry. The 347~488VAC is its input voltage range. LED indicator is not supported by them. They are highly competent in their job. The optimum operating temperature is of the order -40 ℃-85℃.

Moreover, they offer durability and are risk-free.
