ABB - Electrification PSTX720-600-70 - The softstarter PSTX720-600-70 has a rated maximum operational current of 720 A with an operating voltage span from 208...600 V AC. The rated control voltage is between 100...250 V AC at 50/60 Hz. PSTX features a three-phase control soft start and stop through a voltage or a torque ramp. It has built-in bypass for easy installation and energy saving. A RUN, TOR and Event signal is available from relay outputs in NO (normally open state). The PSTX has functions such as current limit, kickstart, analog output, EOL, motor heating and pump cleaning. PSTX also features features jog, braking, stand-still brake, diagnostics, sequence start and emergency/fire pump mode as standard.To interact with PSTX, it has a detachable full graphic display with IP66 and 4x outdoor rating. There are four ways to communicate with PSTX. It can be done by hardwire inputs Start/Stop/Reset of fault, and by three programmable digital inputs. Another popular option is the built-in Fieldbus communication Modbus RTU and incl optional ANYBUS modules with every major protocol such as for example Profinet, Profibus, Modbus TCP, Ethernet IP and others. Another way to communicate with PSTX is to use an external adaptor and a Fieldbus plug. PSTX is the complete alternative for any motor starting application. It’s suitable for medium to large-sized three-phase motors with nominal currents from 30...1250 A inline connection or 52...2160 A inside delta connection. Typical applications are, for example, pumps, fans, compressors, and conveyors.

The ABB PSTX720-600-70 softstarter (SKU: PSTX720-600-70) provides advanced control for medium to large three-phase motors, handling a rated maximum operational current of 720 A. It operates within a broad voltage range of 208 to 600 V AC, with a rated control voltage of 100 to 250 V AC at 50/60 Hz. This softstarter ensures smooth motor start and stop sequences through adjustable voltage or torque ramps, minimizing mechanical stress and extending equipment lifespan. Key features include a built-in bypass contactor, facilitating easy installation and contributing to energy savings by reducing heat during continuous operation. The PSTX720-600-70 offers three programmable signal relays (K4, K5, K6) configurable for Run, Top of Ramp (Bypass), or Event group signals, with a rated operational voltage of 250 V AC/24 V DC and a rated thermal current of 5 A. Integrated functions enhance operational efficiency and reliability, including current limit, kickstart, analog output, end-of-life (EOL) monitoring, motor heating protection, and pump cleaning. Standard capabilities extend to jog, braking, stand-still brake, diagnostics, sequence start, and an emergency/fire pump mode. Interaction is managed via a detachable full graphic LCD display with IP66 and 4x outdoor enclosure ratings, supporting multiple languages. Communication options are extensive: hardwire inputs for Start/Stop/Reset, three programmable digital inputs, built-in Modbus RTU, and optional ANYBUS modules for protocols such as Profinet, Profibus, Modbus TCP, and Ethernet/IP. An external adapter with a Fieldbus plug is also available. The PSTX series is designed for three-phase motors with nominal currents from 30 to 1250 A (inline connection) or 52 to 2160 A (inside delta connection). Typical applications include pumps, fans, compressors, and conveyors. The softstarter supports an overload capability of Class 10 and a starting capacity of 4 x Ie for 10 seconds, with 6 starts per hour for models X300-X1000. It is suitable for operation up to 4000 m altitude (with de-rating) and an ambient temperature range of -25 to 40 °C during operation. The enclosure is rated UL Type 1, 12, 3R, 4.
