QR-SPD06-2IP SPD is an effective combination of metal oxide varistors and a regulated gas discharge tube. This mechanism provides not only a tapered clamping voltage but also a very high surge withstand capacity. There is an inbuilt LED that acts as a replacement notification. 10kA maximum discharge current is granted by this protector. It is also suitable for outdoor luminaires. The ambient temperature ranges from -40 to +70 °C.

This product of QIYUtech is backed by TUV. CE, CQC certifications. Our surge protector is connected parallelly in a circuitry.  It is dust-tight and water-resistant. These surge protector devices are available with Class I or Class II. These two species grant insulation and wire or screw terminal connections.

Furthermore, the product is under IEC 61643-11/EN 61643-11 Standards.
