30 mm 2500 Ohm Potentiometer
The Dayton 30G485 is a 30 mm heavy-duty potentiometer rated at 2500 ohms and 2 watts. It provides a 0 to 100 percent dial plate graduation for precise manual resistance adjustment. The component carries a NEMA 13 rating and a maximum voltage of 500V AC. It is suited for industrial control panels and machinery requiring variable resistance.
Suited for panel-mount control circuits
This potentiometer fits applications needing a 30 mm mounting size and 2500 ohm resistance value. The NEMA 13 enclosure rating protects against dust and spraying water in industrial environments. It is not for circuits requiring higher wattage dissipation or lower resistance values. Buyers needing a different ohm rating or physical footprint should look elsewhere.
2 watt capacity with 500V AC limit
The 2 watt power rating comfortably handles low-power signal and control circuits up to 4 mA. Operation stays within limits at the rated 500V AC maximum. Headroom runs out in high-current driver stages or circuits exceeding the 2 watt dissipation threshold. The 2500 ohm fixed value cannot be altered for other resistance ranges.

Questions about this item
What power supply voltage and dial-plate range does the 30G485 need to operate as intended?
The potentiometer is rated for up to 500 V AC with a 0 to 100 percent dial-plate graduation, so it works directly in circuits within that voltage and control range.
Will the 30 mm body and NEMA 13 rating fit the same panel cut-out and sealing requirements as the unit I am replacing?
It has a 30 mm mounting size and carries a NEMA 13 enclosure rating, matching panels cut for that diameter and providing the same dust and water protection.
How can I verify the 2500 ohm track is functioning correctly after installation?
Measure resistance across the track with a multimeter; it should read close to 2500 ohms and vary smoothly from zero to full scale as the dial moves through the 0 to 100 percent graduations.
