Siemens 3RW4024-1BB14 Sirius Soft Starter

Product Description

The SIEMENS 3RW4024-1BB14 is a SIRIUS series soft starter designed to control the acceleration and deceleration of three-phase induction motors. Soft starters reduce inrush current and mechanical stress during startup by gradually ramping voltage to the motor, extending equipment life and protecting downstream components. This unit is sized for light to medium industrial and commercial motor loads and is installed by licensed electricians and industrial controls technicians in panel or enclosure mount applications. At 1.607 pounds, it is compact enough for space-constrained control panels.

The 3RW4024-1BB14 is used in HVAC fan and pump motor applications, conveyor systems, compressors, and other three-phase motor-driven equipment where across-the-line starting would cause excessive current draw or mechanical shock. It fits into both new installations and retrofit control panel builds where a traditional star-delta or autotransformer starter is being replaced with a more compact solid-state solution.

Key Features

• Solid-state soft start and soft stop control reduces motor inrush current at startup
• Compact form factor at 6.142 x 2.264 x 7.126 inches fits standard control panel layouts
• Lightweight at 1.607 pounds for easy panel integration
• SIRIUS product family design supports consistent panel assembly and replacement sourcing
• Suitable for three-phase induction motor applications in HVAC, pumping, and industrial systems

Compatibility

Designed as an OEM-style soft starter for three-phase motor control panels in commercial and industrial applications. Refer to SIEMENS SIRIUS documentation for full motor current rating and load compatibility before installation.

Installation Notes

Installation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and all applicable local codes. Disconnect and lock out all power to the control panel before handling or wiring the soft starter. Verify that the upstream fusing and wire sizing match the motor full-load amperage rating for this device. Do not apply control voltage until all power wiring connections have been inspected and the enclosure is properly secured.
