Thermally protected surge protectors are transient voltage surge suppression devices specifically designed for outdoor and commercial LED lighting fixtures. They primarily consist of thermally protected varistors and gas discharge tube components. The built-in thermal disconnect function provides additional protection against catastrophic failures and fire hazards, even in extreme cases of varistor failure or sustained overvoltage. This product connects to the LED power supply to offer reliable surge protection, effectively extending the lamp's lifespan and stability. Suitable for Class I or Class II lamps, with protection modes: L-N, L-PE, N-PE. Features a built-in thermal separation function for enhanced safety. Series connection, independent wiring, excellent surge resistance, low residual voltage, compact product size for convenient embedded installation, and IP67 dustproof and waterproof rating. Products are widely used in: road lighting, digital signage, gas station lighting, tunnel lighting, floodlight lighting, AC LED lighting, stadium lighting, traffic lights, harbor lighting, industrial high bay lights. Due to different batches, the printed words on the product may vary, which does not affect its use.
