Allen-Bradley 153H-F251FAD-50 SMC-Flex Solid-State Controller 251A

Product Introduction

When industrial motors face harsh environments and require reliable starting and stopping, the Allen-Bradley 153H-F251FAD-50 solid-state controller delivers robust performance. Part of the SMC-Flex product line, this controller handles high-current applications with a 251 Amp rating and supports up to 200 horsepower at 460V AC. Its IP65 (Type 4/12) enclosure provides significant protection against dust and moisture, making it suitable for demanding industrial settings. This model serves both feeder and control circuit applications with a standard control type.

Technical Specifications Breakdown

The 153H-F251FAD-50 operates on a 230V AC, 3-phase input line voltage at both 50 and 60 Hz. It requires a control voltage of 120V AC. The controller rating is 251 A, 200 Hp at 460V AC, with a rated voltage of 230V AC and a Hp rating of 100. The unit weighs 100.00 lbs (45.36 kg) and is housed in an IP65 (Type 4/12) enclosure. These specifications ensure the controller can manage heavy motor loads while withstanding challenging industrial conditions.

Industry Applications

This solid-state controller excels in applications where motors must start and stop reliably under heavy loads. For example, in conveyor systems handling bulk materials, the 153H-F251FAD-50 provides smooth acceleration and deceleration, reducing mechanical stress on belts and gears. In pump stations for water treatment plants, its robust enclosure protects against moisture and dust, ensuring continuous operation. The controller's 50/60 Hz compatibility makes it versatile for global installations.

Installation & Setup Guidance

When installing the 153H-F251FAD-50, ensure the input line voltage matches the 230V AC, 3-phase supply. Connect the control voltage at 120V AC as specified. Mount the unit securely in a location that allows adequate airflow around the IP65 enclosure. Verify that the motor's horsepower rating does not exceed 200 HP at 460V AC. For feeder and control circuit applications, follow standard wiring practices and consult the manufacturer's manual for detailed connection diagrams.

Maintenance & Reliability

To maximize the service life of the 153H-F251FAD-50, inspect the enclosure regularly for signs of damage or corrosion. Keep the cooling vents clean and free of debris. Periodically check all electrical connections for tightness and signs of wear. The IP65 rating means the unit resists dust and water ingress, but routine visual inspections help catch potential issues early. Following these simple steps reduces unplanned downtime and extends the controller's operational reliability.

Selection Guide & Purchasing Advice

Before purchasing the 153H-F251FAD-50, verify that your application requires a 251 Amp controller with a 200 HP rating at 460V AC. Confirm the input line voltage is 230V AC, 3-phase, and that a 120V AC control voltage is available. This model is ideal for standard control type applications.
