Product Description

Siemens SIRIUS 3RW3013-1BB14 Soft Starter – S00 3.6A, 1.5 kW / 400V

The Siemens 3RW3013-1BB14 is a compact SIRIUS 3RW30 series soft starter (Frame Size S00) engineered for smooth starting of 3-phase asynchronous motors up to 1.5 kW at 400 V (3.6 A). Operating with two-phase control and featuring an integrated bypass contact system, it limits starting current and mechanical torque peaks during motor acceleration. This prevents sudden voltage drops in the supply grid, reduces mechanical shock on gearboxes and belts, and extends equipment lifespan.

Key Features & Technical Details

• Smooth Soft Starting: Reduces high inrush currents and mechanical starting torque, making it an ideal energy-efficient replacement for Direct-On-Line (DOL) and Star-Delta starters.

• Integrated Bypass System: Automatically bypasses the thyristors once the motor reaches full operating speed, significantly reducing heat dissipation inside the control panel.

• Wide Voltage Range: Supports operational line voltages from 200 V to 480 V AC (50/60 Hz) with a versatile control supply voltage of 110 V to 230 V AC/DC.

• Compact Size S00 Footprint: Standard 45 mm module width enables space-saving installation on 35 mm DIN rails alongside SIRIUS 3RV motor starter protectors.

• Adjustable Starting Parameters: Allows manual tuning of the starting voltage ramp (40% to 100% of nominal voltage) and start-up ramp time via rotary potentiometers on the front panel.

• Secure Screw Terminals: Features robust, industrial screw-type terminals for simple, reliable power and control wiring.

Ideal Applications

• Small 3-Phase Motors (up to 1.5 kW / 2 HP at 400V)

• Conveyor Belts & Material Handling Systems (prevents product shock)

• Centrifugal Pumps & Compressors (reduces water hammer and pressure surges)

• Fans, Blowers & Small OEM Machinery

❓ Frequently Asked Questions (FAQs)

Q1: Does the Siemens 3RW3013-1BB14 soft starter include motor overload protection?

A: No, 3RW30 series basic soft starters do not have built-in motor overload protection. They are designed to be paired with a Siemens 3RV2011 Motor Starter Protector (MPCB) or a thermal overload relay (e.g., 3RU21) on the line side.

Q2: What is the main advantage of the integrated bypass contact system?

A: After motor startup is complete, the internal bypass contacts close to bridge the power thyristors. This eliminates ongoing semiconductor power losses during continuous running, minimizing heat build-up inside the cabinet.

Q3: Can this soft starter be used for soft stopping/deceleration?

A: No, the 3RW30 series provides soft starting only. When the control command stops, voltage is removed immediately. For applications requiring soft stopping (such as eliminating water hammer in long pump pipelines), consider the Siemens 3RW40 or 3RW5 series.

Q4: How do I adjust the startup settings on the 3RW3013-1BB14?

A: You can easily set the starting voltage ramp (from 40% up to 100%) and the acceleration ramp time (typically 0 to 20 seconds) using the two rotary potentiometers located on the front face of the module.
