ABB PST(B) Softstarter

Advanced Range

HP: 10HP - 1800HP

Type PST(B) range covers almost all your needs for starting, controlling and protecting your Motors.  The PST(B) ABB Softstarters are very easy to set up using the multi language interface.  For both starting and stopping the motor, ABB offers two alternative settings, voltage ramp or the new torque control where torque control gives an excellent soft stop for pumps among others.  They also include several advanced protections, programmable inputs and outputs and BUS communication, all as standard.  Sizes PSTB370 - 1050 include a built in Bypass Contactor.
