Overview

ABB PSTX Extreme Duty Enclosed Softstarter (SKU: X500-B4-48-XD) delivers heavy-duty motor control for severe industrial environments. This enclosed softstarter combines the PSTX softstarter and TMAX XT breakers in a UL 508A and CSA C22.2 No. 286 certified Type 4 enclosure, rated for NEMA 4 environmental protection. Designed for extreme duty applications, it supports Class 10 starts for Normal Duty up to 600HP/720A and Class 30 starts for Heavy Duty up to 500HP/590A at 480V. The integrated AC-3 emergency bypass ensures critical operations continue during faults, allowing motors to run until scheduled maintenance, minimizing downtime. The unit features a 65kA SCCR rating at 480V and operates across 208–600V AC with rated current up to 1250A. Coated PCBs enhance resistance to harsh conditions, while torque control optimizes performance for pumps and similar loads. The door-mounted interface includes a PSTX keypad with graphical display, Hand-Off-Auto selector, Start/Stop pushbuttons, and pilot lights for Power On, Run, Fault, and Emergency Bypass status. Additional protections include PT-100, earth fault, overvoltage, and undervoltage detection. Current limit options (standard, dual, ramp) and an integrated bypass reduce energy consumption and heat after full speed is achieved, extending equipment lifespan. Pre-assembled for quick installation, this turnkey solution reduces setup time and ensures complete protection for branch circuits and motors in demanding industrial settings.
