TVS Varistors, MOVs, and other devices like the B72500T7151V060 are used to protect sensitive electronic systems from potential damage due to extreme voltage and current. These devices are designed to absorb, divert, and shunt electrical transients that exceed the rated voltage and current of the device, protecting system components from harm.The B72500T7151V060 is a Motor Protection Varistor (MPV) designed for use in motor protection applications. It is a high-current, non-linear device designed to be connected in series with the motor and control power lines. The B72500T7151V060 is designed with an advanced internal clamping circuit that helps reduce the surge current to the protected motor wiring without influencing the motor control signals, allowing for increased protection of the motor without compromising the system performance.The B72500T7151V060 features an operating voltage of 7kV, a peak surge current rating of 5kA, and a maximum peak pulse power rating of 175W. It has a wide operating temperature range of -55°C to 125°C allowing for use in a variety of applications. The B72500T7151V060 also features an extremely low ESD and CDM ratings as well as high insulation resistance, making it ideal for use in ESD sensitive applications.The working principle of the B72500T7151V060 is simple. When a surge or transient voltage passes through the varistor, it is quickly diverted to ground due to its non-linear characteristics. This provides instantaneous protection for the connected load by limiting the voltage flow. The device also has a low resistance path in steady state which also protects the connected load from overload without affecting the normal operation of the system.The B72500T7151V060 is especially useful in CNC machinery, DC step motors, AC induction motors, and other motor-driven devices. Its advanced clamping circuit helps to protect motors and other sensitive system components from damaging transient voltages without affecting system performance.In conclusion, the B72500T7151V060 is a high-performance motor protection varistor designed to provide protection against over-voltage and current surges. Its wide operating temperature range, low ESD and CDM rating, and high insulation resistance make it an ideal solution for motor protection applications. The B72500T7151V060 also features an advanced internal clamping circuit that helps reduce the surge current to the protected motor wiring without influencing the motor control signals, providing increased protection of the motor without compromising the system performance.
