The Siemens part number 3RW4047-1BB14 is a soft start motor starter designed for use with 115 and 230V AC motors. It is part of the EasyStart series, which is known for its advanced and effective soft starting capabilities. This product is particularly useful for applications where a compressor or pump motor needs to operate on a generator, inverter, or limited utility power when it would otherwise not function due to high start-up currents.
The technical specifications of the 3RW4047-1BB14 include:
- Number of poles: 3
- Breaker type: Soft start motor starter
- Start ramp sequence: 4-part sequence that optimizes start-up current reduction
- Start current reduction: Up to 75% of a compressor's LRA (locked-rotor amperage)
- Dimensions: 9.45L x 4.72W x 2.95H in (40L x 120W x 75H mm)
- Wire harness length: 40 in (1m)
The product is designed to be easy to install and use, with a transparent enclosure that allows for easy access to internal components.
