Thermal protection power surge protector is a transient overvoltage protection device specially designed for outdoor and commercial LED lighting fixtures. It is mainly composed of thermal protection varistor and gas discharge tube components. The built-in thermal disconnect function provides additional protection against catastrophic failure and fire hazard even in the extreme case of varistor failure or sustained overvoltage. The product is connected to the LED power driver to provide reliable -surge protection, which can effectively extend the service life and stability of the lamp. Suitable for Class I or Class II lamps, protection modes: L-N, L-PE, N-PE Built-in thermal separation function, higher safety. Series wiring , self-contained leads, excellent surge resistance, low residual voltage, small product size, convenient for embedded installation, IP67 dustproof and waterproof rating. Products are widely used: road lighting, digital signage, gas station lighting, tunnel lighting, flood lighting, AC-LED lighting, stadium lighting, traffic lights, port lighting, industrial high bay lights. Due to different batches, the printed words on the product will be different, which does not affect use.
