ABB Soft Starters

Product Description

Thermal Devices is an authorized distributor for ABB Low Voltage Control Products. The ABB soft starters increase a motor’s lifetime by protecting it from electrical stresses. They do so by letting you optimize starting currents that with conventional starting methods put lots of stress on the motor. ABB’s soft starters are also installation-friendly and can cut your assembly and startup time by being easy to use and easy to learn. With everything that you need in one unit, from bypass contactor to overload protection, a single soft starter makes for a compact and complete starting solution. Furthermore, with many application specific features, ABB’s soft starters can ultimately help you increase productivity. Thermal Devices offers the following ABB soft starters:

PSTX soft starter

The PSTX combines many years of research and product development with extensive knowledge of application specific requirements and needs. The PSTX is our latest advancement in motor control and protection and adds new functionality with increased reliability to any motor starting application.

• Secure motor reliability
• Improve installation efficiency
• Increase application productivity.
• Three-phase controlled
• Operational voltage: 208-690 V AC
• Wide rated control supply voltage: 100-250 V, 50/60 Hz
• Rated operational current: 30…1250 A (inside delta: 2160 A)
• Coated circuit boards
• Torque control for excellent control of pumps.

PST(B) soft starter

The PST(B) softstarter range is the second most advanced softstarter in ABB’s offering after the recently announced PSTX and combines application enhancing functionality with protections for both motor and load. Pre-warnings will even let you act on problems before you need to stop the motor, to avoid unnecessary downtime.

• Built-in motor protections keep your motor safe
• Full-text LCD display in your own language makes installation and setup simple and quick
• Supports most communication protocols with the accessory FieldBusPlug
• Torque control improves control of pumps and prolongs equipment lifetime
• Bigger sizes feature built-in bypass which reduces energy consumption during application full speed.
• Rated operational current: 30 to 1050 A (inside delta 1810 A)
• Operational voltage: 208–690 V AC
• Control supply voltage: 100–250 V, 50/60 Hz
• In-line and inside-delta connection.

PSE soft starter

Our PSE range is the perfect compromise between size and functionality. With torque control, it is the perfect option for smaller sized pump applications.

• Keep your motor safe with built-in motor protections
• Fast and easy set-up with illuminated, language-neutral display
• Eliminate water hammering with torque control
• Reduce energy losses with built-in bypass.
• Rated operational current: 18 to 370 A
• Operational voltage: 208–600 V AC
• Control supply voltage: 100–250 V AC.

PSR soft starter

The PSR softstarter range is a simple yet reliable starting solution that utilizes only the most basic of soft starting features: soft start and stop. It performs well in applications requiring many starts per hour and is perfect for installations where you need to save space.

• Small and compact starting solution
• Can perform many starts per hour
• Reduce energy loss at full speed with built-in bypass.
• Rated operational current: 3 to 105 A
• Operational voltage: 208–600 V AC
• Control supply voltage: 24 V AC/DC or 100–240 V AC.

PSS soft starter

The PSS range offers in-line and inside delta connections.
Current limit can be activated using an external current transformer.

• Easy-to-use alternative
• In-line and inside-delta connections
• Quick to install and to get running
• Handles many starts per hour.
• Rated operational current: 18 to 300 A (inside delta 515 A)
• Operational voltage: 208–690 V AC
• Control supply voltage: 110–120 V AC or 220–240 V AC
• In-line and inside-delta connection.
