| Inverter (VFD) Model Naming Rules | ||||||||
| Although the rules vary slightly between different series, taking ACS580-01-09A8-4 as an example, its structure is usually as follows: | ||||||||
| ACS:The product series prefix represents ABB frequency converters. | 580:Product serial numbers, such as 580 (general type), 880 (high-end type), 580. | |||||||
| 01:Hardware version or structure code. 01 typically indicates a wall-mounted unit with an IP21 protection rating. 04 may indicate an IP55 protection rating, and 11 may indicate a modular unit. | 09A8:Rated current. This indicates that the device's rated output current is 9.8 amps. This is a key parameter for selection. | |||||||
| 4:Voltage levels: 2 = 208-240V, 4 = 380-480V, 6 = 525-690V. | Example of a complete model: ACS880-01-414A-3+E200+P904 indicates an ABB ACS880 series frequency converter with a rated current of 414A and a voltage of 400V, and includes options such as an expansion card. | |||||||

| ABB SS (Soft Starter) Product Overview: | ||||||||
| soft starter (SS) is a motor control device that integrates soft starting, soft stopping, light-load energy saving, and multiple protection functions. Unlike a frequency converter, a soft starter only controls the starting and stopping process of the motor; during normal operation, the motor operates at the power frequency. | ||||||||
| Series Overview Comparison | ||||||||

| Soft starter (SS) model naming rules | ||||||||
| ABB soft starters have a standardized model format, such as PSR37-600-70 or PSTX105-600-70, which can be interpreted as follows: | ||||||||
| PSR / PSE / PSTX: Product seriesThis represents the functional level of the soft starter. | ||||||||
| PSR:Compact and economical. | PSE:Highly efficient and compact, with torque control. | |||||||
| PSS:General and flexible. | PST(B):Advanced intelligent type. | |||||||
| 37 / 105: Rated current:It is the maximum continuous operating current of the soft starter, measured in amperes (A), and is the core basis for selection. | 600: Main circuit voltage:This indicates that the device's rated operating voltage is 600V AC. Common options are 600 (maximum 600V) and 690 (maximum 690V). | |||||||
| 70 / 11: Control voltage code. | ||||||||
| 70:This indicates that the control voltage is 100-240V AC. | 11:This indicates that the control voltage is 24V AC/DC. | |||||||
| Complete model example:PSTX370-600-70 indicates an ABB PSTX series advanced intelligent soft starter with a rated current of 370A, a main circuit voltage of 600V, and a control voltage of 100-240V AC. | ||||||||
