The Siemens 3RT1034-1BB44-0AA1 is a robust and reliable power contactor designed to handle a variety of applications in industrial environments. This contactor is part of the SIRIUS product family, known for its high-quality performance and durability. With a size S2 frame, the device is compact yet powerful, capable of switching motors up to 15 kW at 400 V in AC-3 usage categories.
This model features a 24 V DC control supply voltage, making it suitable for direct current control systems. It comes with three poles and includes both normally open (NO) and normally closed (NC) auxiliary contacts, specifically 2NO + 2NC, which are useful for implementing control logic circuits. The screw-type terminals provide a secure and reliable connection for both the main and auxiliary circuits.
The contactor is designed for easy mounting, with options for screw and snap-on mounting onto a 35 mm standard mounting rail according to DIN EN 50022, allowing for side-by-side installation. It has an IP20 protection class on the front, ensuring that the contactor is protected against touch and foreign objects.
With a mechanical operating life of around 10 million cycles, the Siemens 3RT1034-1BB44-0AA1 is built to last and perform consistently in demanding conditions. Its ambient temperature operating range of -25 to +60 °C makes it versatile for use in various climates and industrial settings.
The contactor's design also includes a built-in varistor for surge suppression, enhancing the protection of the coil from voltage spikes. This feature contributes to the longevity and reliability of the device in fluctuating voltage environments.
Overall, the Siemens 3RT1034-1BB44-0AA1 is a high-quality component that offers reliability and efficiency for controlling electric motors and loads, making it a valuable addition to any industrial control system.
