Product Details
Specifications provided for reference. Verify critical details against official manufacturer documentation before installation.
Product Overview
The 3RW5227-1AC14 is a Siemens SIRIUS 3RW52 series general-performance soft starter, designed for controlling three-phase asynchronous motors with reduced starting current and torque. It operates on line voltages between 200 and 480 V AC and uses a control supply of 110-250 V AC. The unit integrates an analog output, standard HMI support, and an internal bypass contact system, facilitating motor ramp-up and ramp-down in industrial applications such as pumps, conveyors, and compressors.
Best Suited For
- Soft starting of three-phase motors (up to 93 A)
- Applications with controlled starting/stopping (e.g. conveyors, fans, pumps)
- Systems requiring analog output for monitoring
- Installation with standard HMI modules
- Environments needing integrated bypass switching
