Siemens Industrial Controls 3RW4027-1BB15 Starter
The Siemens 3RW4027-1BB15 Sirius Soft Starter is a compact, solid-state solution designed for the smooth starting and stopping of three-phase asynchronous motors. Engineered for high-performance applications, this 32A soft starter operates on a 230V control voltage and is rated for motors up to 15 HP at 460V. Utilizing two-phase control technology, it effectively minimizes current peaks and torque surges during startup, reducing mechanical stress on belts, gears, and couplings. The integrated bypass contact system engages after the motor is up to speed, significantly lowering heat dissipation and eliminating the need for external bypass contactors. Built-in features include electronic motor overload protection and intrinsic device protection to prevent thermal overloads. This S0 frame size unit features screw terminals for secure power and control wiring terminations, making it a reliable choice for centrifugal pumps, screw compressors, and conveyor systems requiring precise reduced voltage starting.
Key Benefits for the Jobsite:- Integrated Bypass Contacts: Reduces internal heat generation and energy consumption during steady-state operation.
- Adjustable Current Limiting: Prevents voltage drops and protects the facility grid from high inrush currents.
- Compact S0 Footprint: Saves critical DIN rail space in control cabinets compared to traditional star-delta starters.
- Remote Reset: Allows for quick fault clearing without opening the enclosure, minimizing downtime for the end user.
- Motor Overload Protection: Eliminates the cost and installation time of an additional thermal overload relay.
How do I set the ramp time and start voltage?
The 3RW4027-1BB15 features three potentiometers on the front face for adjusting the ramp-up time, starting voltage (typically 40% to 100%), and current limiting levels to match specific load requirements.
Can this unit be used for soft stopping?
Yes, this model supports an adjustable ramp-down time, which is essential for preventing water hammer in pumping applications and protecting fragile products on conveyor belts.
What is the maximum ambient temperature for rated operation?
This starter is engineered for performance up to 40 degrees Celsius without derating. For higher temperature environments, the maximum operating current must be adjusted per the manufacturer's derating curves.
