Allen-Bradley 152H-F25FAD-37 SMC-Flex Solid-State Controller with Fusible Disconnect

Product Introduction

When harsh industrial environments demand reliable motor control, the Allen-Bradley 152H-F25FAD-37 SMC-Flex solid-state controller with fusible disconnect delivers robust performance. This unit combines a solid-state motor starter with an integrated fusible disconnect switch, all housed in an IP65 (Type 4/12) enclosure. Designed for three-phase applications requiring 230V AC input at 50 or 60 Hz, it provides a controller rating of 25 A and 15 Hp at 460V AC. The 120V AC control voltage simplifies integration with existing control systems. Part of the trusted SMC-Flex family, this controller offers a compact, durable solution for demanding applications.

Technical Specifications

The 152H-F25FAD-37 operates on a 230V AC, 3-phase input line at both 50 and 60 Hz. Its controller rating is 25 A, supporting motors up to 15 Hp at 460V AC. The control voltage is 120V AC, and the rated voltage is 230V AC. The enclosure meets IP65 (Type 4/12) standards, providing protection against dust ingress and water jets. Weighing 100.00 lbs (45.36 kg), this unit is built for permanent installation in industrial settings. The bulletin number confirms it as a solid-state controller with fusible disconnect. These specifications ensure reliable starting and stopping of motors in demanding conditions.

Industry Applications

This controller excels in applications where space is limited and environmental protection is critical. Use it in pump stations, conveyor systems, and HVAC equipment within factories or outdoor installations. The IP65 enclosure allows installation in washdown areas or dusty environments without additional cabinets. For example, a food processing plant can mount this unit directly on a production line to control a 15 Hp conveyor motor, benefiting from the integrated disconnect for safe maintenance. The 50/60 Hz compatibility makes it suitable for global installations.

Installation & Setup Guidance

Mount the 152H-F25FAD-37 securely on a flat surface using the provided mounting holes. Ensure adequate clearance around the enclosure for heat dissipation and access to the disconnect handle. Connect the three-phase input line (230V AC, 50/60 Hz) to the line-side terminals of the fusible disconnect. Connect the motor load to the load-side terminals. Wire the 120V AC control voltage to the control circuit terminals as per the wiring diagram on the enclosure label. Verify all connections are tight and the disconnect is in the OFF position before applying power. For detailed wiring instructions, refer to the product manual.

Maintenance & Reliability

Regular inspection of the 152H-F25FAD-37 ensures long service life. Check the enclosure seals for damage and verify the disconnect mechanism operates smoothly. Periodically clean the exterior with a dry cloth to prevent dust buildup. The solid-state design eliminates contact wear, reducing maintenance frequency compared to electromechanical starters. The IP65 enclosure protects internal components from moisture and contaminants, enhancing reliability in harsh environments. If the unit fails to operate, verify input power and control voltage before inspecting internal fuses. For any internal repairs, contact a qualified technician.

Selection Guide & Purchasing Advice

Before purchasing the 152H-F25FAD-37, confirm your motor's full-load current does not exceed 25 A and that your supply voltage matches 230V AC three-phase. Verify the control voltage requirement is 120V AC. This unit is not suitable for applications requiring variable speed control.
