main feature

Smooth start and stop:

The soft starter starts the motor smoothly by gradually increasing the motor voltage, effectively reducing the impact on the power grid and reducing the mechanical stress on the motor.

Likewise, smooth deceleration can be achieved when stopping, avoiding mechanical shock caused by sudden stops.

Fault identification and protection:

It has multiple fault identification capabilities, such as power supply or phase failure, load loss, impermissible trip time/level setting, thermal overload or equipment failure, etc.

Internal intrinsic device protection is provided to prevent thyristor thermal overload and power defects.

Integrated features:

It integrates functions such as adjustable current limit and motor overload protection, eliminating the need to purchase and install external protection equipment such as overload relays.

With thermistor motor protection options, you can choose according to your needs.

Small space footprint:

The design is compact and takes up little space, making it especially suitable for control cabinets with limited space.

The integrated bypass contact means that there is no need to consider the power consumption of the power semiconductor after the motor is started, reducing heat losses.

Monitoring and Diagnostics:

Use 4 LEDs and relay outputs to indicate working status and various fault information.

Provides rich diagnostic functions to quickly locate and solve problems.

Easy to install and debug:

The number of cables required to connect the starter to the motor is reduced from six to three, simplifying wiring work.

Short start-up times and quick commissioning make installation and commissioning easier.

Application scenarios

Siemens 3RW4038-1BB14 soft starter is suitable for various occasions that require smooth starting and stopping of motors, such as fans, water pumps, compressors, etc. Its excellent performance and reliable protection function make it the preferred product in the field of industrial automation.

Summarize

Siemens 3RW4038-1BB14 soft starter has been widely used in the field of industrial automation due to its smooth start and stop, fault identification and protection, integrated functions, small space occupation, and easy installation and debugging. It is a trustworthy product both in terms of performance and reliability. If you need this product, you can contact us!
