ABB PSS Softstarter
The softstarter range PSS18/30 ... PSS300/515 is a very flexible solution suitable for most applications and for replacements of Star-Delta starters. Since the unit can be connected inside the motor delta (compare the connection for standard Star-Delta starters), the current through the softstarter is reduced by 42 %. It will then be possible, for example, to run a 100 A motor using a 58 A PSS Softstarter.
In-Line and Inside Delta connection of PSS18/30 … PSS300/515
- Wide main voltage range 208 - 690 V AC
- Supply voltage range 110-120 V AC and 220-240 V AC
- Current ratings 18 ... 300 A (In Line) and 30 ... 515 A (Inside Delta)
- Same unit can be used for both In Line and Inside Delta connection
- Start ramp, Stop ramp and Initial voltage included
- Current limit function as option
- Solid state electrical circuit
- Designed for continuous operation without by-pass
- 15% overcurrent capability during continuous run (10 % for PSS300/515)
- Accessories for connection and installation available
The PSS Softstarter can be selected according to the rated motor power in normal duty applications like pumps, compressors, elevators, escalators, short conveyor belts and bow thrusters.
For heavy duty applications like centrifugal fans, crushers, mixers, mills, stirrers and long conveyor belts, select a softstarter.

* If using MCCB only, type 1 coordination will be achieved
** To achieve a type 2 coordination, semi-conductor fuses must be used
*** Suitable switch fuse for recommended semi-conductor fuses.
**** The line contactor is not required for the softstarter itself but often used to open if OL trips
***** The overload relay is always required to protect the motor
****** The by-pass contactor can be used to reduce the power loss of the softstarter but also to increase the number of starts/h. All softstarters can be operated without by-pass.
******* Must be used if current limit function is required
