  • Technical data & Specification
  • Outline drawings

They guarantee protection of the electronic fluorescent and HID ballasts. They are yielded in the insulation of Class I luminaries.


These economical gizmos offered by our company are under IEEE C62.41 Category C Low Exposure. These compact devices are a single-phase gadget with the L to N, L to Ground and N to Ground protection function. It is relatively more central and suitable for the current LED design specifications due to its unlimited load power. It is parallelly connected in circuitry. The input voltage spreads over 120-277VAC. The current discharge offered by this surge protector is 10kA.

A certain protective function must be installed along with their induction in circuitry to circumvent sparks or any kind of crash. Furthermore, their ambient temperature has a broad spectrum and lies within the range -40 ℃ 85℃.
