3RW4747-0NC00 SIEMENS

The 3RW4747-0NC00 Siemens power semiconductor module is an essential component designed for soft starters, specifically tailored for use with the 3RW4447 model. This module incorporates a negative temperature coefficient (NTC) thermistor, which provides temperature-dependent resistance, crucial for thermal management and protection. With a voltage rating of 690 V, it is suitable for applications within this voltage range, ensuring compatibility and safety. The module is engineered to handle a current of 432 A, making it capable of managing substantial electrical loads. Its primary function is to regulate the voltage during motor start-up, reducing stress on the motor and connected equipment. By controlling the inrush current, it prevents voltage dips and extends the lifespan of the motor. The NTC element enhances the soft starter's ability to respond to temperature changes, preventing overheating and potential damage. This module is a reliable solution for motor starting applications, offering both performance and protection. It is ideal for industrial environments where motor control and protection are paramount.
