Description
Type PST(B), covers motor currents from 30 to 1050 A and
provides advanced functionality, including integrated protections, programmable signal relays, a flexible communication
system and an LCD display. Sizes PSTB370 to 1050 A include
a by-pass contactor.
• Advanced integrated protections: For the motor; integrated electronic overload relay, phase monitoring relays,
high current and PTC protection. For the Softstarter; advanced thyristor protection.
• Flexible bus communication system: By using the ABB
FieldBusPlug (FBP), you can decide at any time which bus
system to select within the ABB FBP range. The interface
between the PST Softstarter and the ABB FBP is always the
same, independent of size and delivery date.
• LCD display: With 14 languages, a menu system
similar to your mobile phone, preprogrammed application
settings and automatic status and event logging, it couldn’t
be easier to set up and operate!
• Programmable signal relays: gives you several possibilities for signalling warnings, faults and other events.
• Torque control: allows you to start and stop motors with
a more linear acceleration than when using voltage ramp.
