Product Overview
For maintenance engineers managing motor control in demanding environments, the Allen-Bradley 152H-F25FAD-37 SMC-Flex solid-state controller delivers robust performance with integrated fusible disconnect protection. This unit is built to handle 25 A continuous current and 15 Hp at 460V AC, housed in an IP65 (Type 4/12) enclosure that resists dust, moisture, and washdowns. The fusible disconnect simplifies installation by combining overcurrent protection and disconnecting means in one package, reducing panel space and wiring complexity.

Industry Applications
Use it for starting and stopping three-phase motors in pump stations, conveyor systems, and HVAC equipment. The fusible disconnect provides a local means of isolating power for safe maintenance, reducing downtime during troubleshooting.
Installation & Setup Guidance
Mount the unit on a flat, vertical surface using the provided flanges. Ensure the enclosure lid seals properly to maintain IP65 integrity. Connect three-phase input power (230V AC, 50/60 Hz) to the line terminals, and the motor to the load terminals. Wire the 120V AC control voltage to the control circuit terminals per the wiring diagram on the inside cover. Size the fuses according to the motor full-load current and local codes. Verify all connections are tight before applying power.
Maintenance & Reliability
Periodically inspect the enclosure gasket for cracks or compression set to maintain the IP65 seal. Check the disconnect handle for smooth operation. Clean the exterior with a mild detergent and water; avoid high-pressure spray directly at the gasket. Monitor the controller’s operating temperature; ensure ambient conditions stay within the unit’s rating. Replace fuses only with the same type and rating. No internal adjustments are required under normal use.
Compatibility & Integration
The 152H-F25FAD-37 is a standalone solid-state controller with fusible disconnect. It integrates directly into any 230V AC three-phase system without additional communication modules. The standard control type accepts simple start/stop commands from a pushbutton station or PLC discrete output. For advanced motor protection and diagnostics, pair with an external overload relay or motor protection circuit breaker.
Selection Guide & Purchasing Advice
When selecting this controller, confirm your motor’s full-load current does not exceed 25 A and that your supply voltage matches 230V AC three-phase. The 15 Hp rating at 460V AC indicates the unit can also be used on 460V systems with appropriate derating. Contact AutoDCSTech for current pricing and lead time. Please verify current lifecycle status and availability with AutoDCSTech before ordering.
Troubleshooting & Common Issues
If the motor fails to start, check the control voltage (120V AC) and the condition of the fuses. Verify the disconnect handle is in the ON position. If the unit trips repeatedly, inspect for motor winding faults or excessive load. Ensure the enclosure lid is closed properly to prevent moisture ingress. For persistent issues, consult the SMC-Flex user manual or contact AutoDCSTech technical support.
