The Allen-Bradley 150-F251FBD is a solid-state controller. It features an IP65 (Type 4/12) enclosure. It has a voltage line ranging from 400-460V AC. It has a current rating of 251 A. Its controller rating is 460V AC at 200HP. Its input is 50 and 60 Hz. This controller also has a three-phase cage induction. It also has an embedded motor overload protection which protects it from excessive currents. This solid-state controller aids in minimizing costs and enhancing scalability. It does this through its simple controls for starting, stopping, and adjusting settings.

The 150-F251FBD can be used for controlling loads that are resistive. It also has three standard operating modes which are the soft start, the full voltage start, and the current limit start. It has a special energy saver feature that saves energy when the 150-F251FBD is lightly loaded on applications. Other optional features include the pump control, the ability to slow with braking, and the accu stop. These can be configured if the user needs to use them to perform various operations. The 150-F251FBD can be wired with or without a motor starter if it is configured with the rotary digital switches and with the DIP switches.

The 150-F251FBD contains a thermostat that helps to control its temperature. Its operating temperature should not exceed 50°C. A temperature above that may cause damage to the device. It contains additional stall protection. Auxiliary contacts embedded in this device also aid in supporting instantaneous operations. The two-wire and three-wire control in it lets it support many operations undertaken by the user. The 150-F251FBD also has LEDs which show the user various operations like running mode, a temperature fault, and the stopping mode. It should be kept in an environment that is free from dust.
