Surge Protection Device

RS DR50 ctrl 1.0 Encapsulated and Triggered Lightning protection device is a 1 pole, high energy loaded voltage switching type surge Protective devices, with compact structure, high discharge capability, low voltage protective level, quick response, little follow current. By virtue of the advanced electronic trigger and ingenious encapsulated discharge spark gap, the lightning protector used a class I (B) SPD, ca be directly connected in parallel with Class II (C) SPD, without requirement of cable lengths or decoupling coil. This results in a coil between them, also not considering work current limit of the additional coil. This results in a space saving, simplifying installation technology and optimizing complex wiring. The spark gap is a precisely made by alloy material with excellent arc ablation resistance, whose ignited voltage can be controlled by electronic trigger, it also can be ignited and discharges most surge energy thorough gap, when suppression voltage on Class II (C) SPD connected directly in parallel with lightning arrester during suppressing reach up to preset triggered voltage value, for transmitting and decreasing the load on Class II (C) SPD, accordingly accomplishes the energy coordinator of Class I (B) and II (C) SPD. The coordinating precondition is that Class II (C) SPD must be based on a varistor with a suitable clamping rated voltage.
