Dayton 30G487 Potentiometer
This Dayton 30G487 is a 30 mm heavy-duty potentiometer rated at 10,000 ohms with a 2 W power dissipation. It suits industrial control panels, test equipment and machinery where a robust variable resistor is required. The component carries a NEMA 13 rating for protection against dust and spraying liquids.
Installation and common issues
The unit mounts in a standard 30 mm panel cutout and terminates with solder lugs for straightforward wiring. Ensure the circuit voltage stays within the 500 V AC maximum and current does not exceed 4 mA to avoid overheating. Incorrect orientation of the 0 to 100 percent dial plate can reverse the control direction.
Capacity and headroom
At 2 W and 10,000 ohms the potentiometer comfortably handles low-level signal adjustment and reference voltage trimming. It runs out of headroom in high-power driver stages or circuits demanding more than 4 mA through the wiper. The NEMA 13 enclosure does not protect against submersion or prolonged high-pressure washdown.

Questions about this item
How can I verify the 30 mm potentiometer is operating correctly after installation?
Measure resistance across the terminals with a multimeter; it should read 10,000 ohms at full rotation and track smoothly from 0 to 100 percent dial graduations.
What accessories are included with the Dayton 30G487 and what must be purchased separately?
The unit ships with the potentiometer body and 0 to 100 percent dial plate; mounting hardware, wiring and a control knob are not included and must be sourced separately.
Which specification should I match when selecting this 30 mm model for my circuit?
Choose this version when your design requires a 2 W, 10,000 ohm potentiometer rated for 500 V AC, 4 mA maximum current and NEMA 13, 4 enclosure rating.
