3TX4490-2F SIEMENS

The 3TX4490-2F adapter from Siemens serves as a crucial interface, facilitating both mechanical and electrical connections between a 3VU13 circuit breaker and a 3TF20 contactor. This adapter, with a standardized width of 45 mm, ensures seamless integration of these components within a control panel or electrical system. Its primary function is to provide a stable and secure mounting platform for the 3VU13 circuit breaker onto the 3TF20 contactor. Electrically, the adapter establishes the necessary connections for control and signaling circuits, enabling coordinated operation between the circuit breaker and contactor. This coordinated operation is vital for motor starting applications, where the circuit breaker provides overload and short-circuit protection, while the contactor controls the motor's on/off state. The 3TX4490-2F adapter simplifies the assembly process, reducing wiring complexity and minimizing the risk of errors. By using this adapter, engineers and technicians can achieve a compact and reliable motor control solution. Furthermore, the adapter's robust design ensures long-term durability and resistance to environmental factors commonly encountered in industrial settings. Siemens' commitment to quality is evident in the adapter's precise construction and adherence to industry standards, guaranteeing optimal performance and safety.
