Square D 9001SK2105 Potentiometer 1000 Ohm 30mm Nema 4

Product Description

The SQUARE D 9001SK2105 is a 1,000-ohm industrial potentiometer rated for 300 VAC and 2 watts of power dissipation. Designed for panel-mounted control applications, it uses a 30mm mounting hole diameter and is operated by a knob, making it suitable for manual speed, voltage, or signal adjustment in industrial control circuits. The unit carries a NEMA 4 and NEMA 13 enclosure rating, meaning the operator and mounting hardware are built to resist windblown dust, rain, splashing water, and oil. Licensed electricians and industrial control technicians are the primary installers for this type of component.

This potentiometer fits standard 30mm panel cutouts and is used in industrial and commercial control panel applications where manual analog adjustment is required. Typical installations include motor speed control loops, signal conditioning circuits, and operator interface panels on production equipment. The nonilluminated knob-operated design suits environments where backlighting is not required and a clean, low-profile operator is preferred. It is suited for both new panel builds and replacement of worn or failed potentiometer operators in existing enclosures.

Key Features

• 1,000-ohm resistance with 2-watt power rating for reliable analog signal control
• 300 VAC voltage rating supports standard industrial control circuit voltages
• 30mm mounting hole diameter fits standard industrial panel cutouts
• NEMA 4 and NEMA 13 ratings provide protection against water, dust, and oil ingress
• Nonilluminated, knob-operated design for straightforward manual adjustment
• RoHS compliant construction

Compatibility

Designed as an OEM-style replacement or new-installation potentiometer for 30mm industrial control panels requiring a 1,000-ohm, 300 VAC, NEMA 4 and NEMA 13 rated operator.

Installation Notes

Installation should be performed by a licensed electrician or qualified control panel technician in accordance with the National Electrical Code (NEC). De-energize and lock out the control panel before beginning any wiring or mounting work. Verify the panel cutout diameter matches 30mm before installation. Do not exceed the 2-watt or 300 VAC ratings for this device.
