ABB X500-B4-48-XD PSTX Enclosed 500HP Motor Protection System with Advanced Torque Control and Extreme Duty Features

The ABB X500-B4-48-XD PSTX Enclosed 500HP XD N4 is a robust motor protection solution designed to enhance the reliability and efficiency of your motor systems. This all-in-one unit is equipped to manage load and network irregularities, offering comprehensive protection features such as PT-100, earth fault protection, and over/under voltage protection. With three types of current limit—standard, dual, and ramp—you gain precise control over motor start-up, even in weaker networks. The built-in bypass simplifies installation and conserves panel space. The PSTX is packed with application-enhancing features, including advanced torque control for optimal pump start and stop operations, and a pump cleaning function that reverses flow to clear pipes, ensuring maximum uptime. Key benefits include securing motor reliability, improving installation efficiency, and boosting application productivity. Main features include three-phase control, operational voltage range of 440 to 480 V AC, and a wide rated control supply voltage of 100-250 V, 50/60 Hz. It supports a rated operational current of 15 to 1250 A and features coated circuit boards for durability. Additional features for normal and heavy-duty applications include a circuit breaker or fuses, door-mounted keypad, start and stop pushbuttons, a hand-off-auto selector switch, and pilot lights for power, run, and fault status. Extreme duty features add an emergency bypass, normal-E-bypass selector switch, and E-bypass pilot light, ensuring comprehensive control and safety in demanding environments.
