The Siemens 3RA1125-1BA23-1AK6 Combination Starter is a versatile electrical component designed for use in industrial and commercial applications where motor control and overload protection are required. This non-enclosed starter comes with a 120/110VAC, single-phase, 60Hz power supply, making it suitable for use in North American electrical systems.
The 3RA1125-1BA23-1AK6 Combination Starter is a SPDT (Single Pole Double Throw) type, meaning it can switch a single load between two sources. The primary function of this starter is to control the starting and stopping of an electric motor, while also providing overload protection for the motor against excessive current.
This starter features a mechanical overload relay, which is designed to trip if the motor current exceeds the rated value. The mechanical overload relay is located within the starter body and is operated via a thermal element. When the motor current becomes too high, the thermal element expands, causing the contacts to open, thereby disconnecting the motor from the power supply. This helps prevent the motor from being damaged due to overloading.
The Siemens 3RA1125-1BA23-1AK6 Combination Starter is equipped with a number of other protective features, including short circuit protection and overvoltage protection. The short circuit protection ensures that the starter disconnects the motor from the power supply in the event of a short circuit, while the overvoltage protection prevents the motor from being subjected to voltages higher than the rated value.
The starter is also designed to be easy to install and maintain. It comes with a number of terminals for connecting the various components, including a separate terminal for the overload relay. The terminals are clearly labeled, making it easy to identify where each wire should be connected.
The Siemens 3RA1125-1BA23-1AK6 Combination Starter is built to high standards of quality and reliability. It is made from robust materials and is designed to withstand the rigors of industrial and commercial applications. The starter is also UL listed, meaning it has been tested and certified to meet the safety and performance standards set by Underwriters Laboratories.
In summary, the Siemens 3RA1125-1BA23-1AK6 Combination Starter is a versatile and reliable electrical component that is ideal for use in industrial and commercial applications where motor control and overload protection are required. It is a single-phase, 120/110VAC, SPDT starter with mechanical overload protection, short circuit protection, and overvoltage protection. It is easy to install and maintain, and is built to high standards of quality and reliability.
