The BSP3-347 is a lighting protection device that is used in industrial applications. It is a metal oxide varistor (MOV) that is designed to protect against electrical surges. It is typically placed in series between a power line and the electrical appliance or distribution panel it is protecting. In the event of an electrical surge, the BSP3-347 will absorb the surge energy, thereby limiting the amount of energy that reaches the appliance or panel.The BSP3-347 has a breakdown voltage of 330V and a maximum voltage of 400V. This means that it will remain in a non-conductive state until the voltage on the line reaches 330V, at which point it will begin to conduct. The breakdown voltage is selected so that it is always higher than the normal working voltage of the line, so that the protection device will not be triggered during normal operation. At the same time, the maximum voltage is selected to be lower than what is expected from even the most severe surge events.The working principle of the BSP3-347 is simple. When the voltage on the line reaches the device\'s breakdown voltage, the device begins to conduct. This creates a low resistance path which allows the excess energy from the surge to be directed safely away from the appliance or panel. As the surge passes, the voltage on the line drops back to its normal levels, at which point the device returns to its non-conductive state.The BSP3-347 is a powerful surge protection device that is often used in industrial applications. Its combination of low breakdown voltage and high maximum voltage makes it ideal for protecting sensitive electrical equipment from large and sudden surges. The device is also relatively inexpensive and easy to install, making it a viable option for many industrial applications.
