509-CEB-A2J-1-4G

The part number 509-CEB-A2J-1-4G is a magnetic motor starter that Allen Bradley has developed to handle a robust range of motor control functions. This unit operates effectively at a control voltage rating of 460–480 V AC with a frequency of 60 Hz. Designed to support continuous current levels of up to 45 A, it is capable of managing motors with a maximum horsepower of 25 HP efficiently.

The product features an impressive maximum circuit-closing inrush current of 483 A, which is essential for starting large motors under load. It also incorporates a built-in overload relay, providing necessary protection against potential motor overload conditions. Furthermore, this starter offers eight auxiliary contacts, enabling additional control and monitoring capabilities.

Connection of this starter is achieved through pressure terminals, which ease the installation process. The power-terminal wire size range compatible with this starter spans AWG 14 to AWG 4, which allows for flexibility in wiring. In terms of operational timings, the pickup time is 27 milliseconds, and the drop-out time is recorded at 13 milliseconds.

With an operational temperature range of -25 °C to +55 °C, this unit is designed to perform reliably in a variety of environments. The service-limit current rating rests at 52 A, providing a buffer for handling momentary surges. The nominal supply voltage can range widely from 115 to 575 V AC, ensuring adaptability across multiple applications.
