What Is the 152H-F25FAD-37?
The Allen-Bradley 152H-F25FAD-37 is a solid-state controller from the SMC-Flex product line, built with an integrated fusible disconnect. It manages motor starting and stopping without the wear of traditional electromechanical contactors. With a 25 A controller rating and 15 Hp at 460V AC, it fits demanding industrial duty.
The IP65 (Type 4/12) enclosure lets you mount it in dusty or washdown-prone areas without a separate cabinet. The unit accepts 230V AC, 3-phase input at 50 and 60 Hz, with a 120V AC control voltage.

What the Ratings Mean in Practice
The 25 A rating sets the current ceiling for the connected motor circuit. The 15 Hp at 460V AC figure tells you the controller handles medium-horsepower loads on that supply. The 120V AC control voltage matches common plant control circuits, simplifying panel integration.
Where the 152H-F25FAD-37 Fits
Oil and gas operations often run motors in wet, dirty, or outdoor locations. The IP65 enclosure resists dust ingress and water spray, so the controller can sit closer to the process. Pump jacks, compressor drives, and conveyor motors are typical candidates.
In water treatment and food processing, washdown routines punish standard enclosures. Type 4/12 construction survives those conditions and reduces premature failures. That translates into fewer unplanned stoppages and lower maintenance spend.
Because the unit combines a fusible disconnect with solid-state control, you get short-circuit protection and controlled starting in one package. That saves panel space and wiring time during installation.
Installation and Setup Notes
Mount the controller on a rigid surface that can carry 100.00 lbs (45.36 kg). Allow clearance for cable entry and heat dissipation. Verify that your supply matches 230V AC, 3-phase at 50 or 60 Hz before energizing.
Confirm the control circuit delivers 120V AC to the appropriate terminals. Follow the manufacturer’s wiring diagrams for line, load, and control connections. Torque terminations to the values in the installation manual.
If you plan to tie the controller into a plant network, note that fieldbus integration may require an external gateway or connection module. Confirm cables and gateways with your supplier before ordering.
Maintenance and Reliability
Solid-state controllers have no moving contacts to pit or replace, so routine work focuses on the enclosure and connections. Inspect the gasket and seals periodically to preserve the IP65 rating. Check terminal torque and look for signs of overheating during scheduled shutdowns.
Keep the heat sink fins clear of dust and debris. In oil and gas environments, airborne hydrocarbons can coat surfaces over time, so include the controller in your cleaning schedule. Follow the manufacturer’s safety manual for all service activity.
Please verify current lifecycle status and availability with Oil AutoTech before ordering.
Buyer’s Checklist
Before you commit, confirm the motor horsepower and full-load current fall within the 25 A, 15 Hp at 460V AC rating. Match your available supply to the 230V AC, 3-phase input. Check that your control circuit provides 120V AC.
Measure your mounting space against the 100.00 lbs (45.36 kg) unit and plan for cable bend radius. If you need spares when you need them, Oil AutoTech offers fast dispatch, worldwide. Contact Oil AutoTech today for pricing and availability.
