Schneider Electric 9001L31 Pilot Light Lens Blue NSMP

Schneider Electric's Square D 9001L31 blue 30 mm pilot light lens is a plastic Fresnel replacement cap designed for Harmony 9001K and 9001SK pilot lights. Molded from durable plastic and measuring 30 mm in diameter, this lens fits standard 30 mm panel-mount pilot indicators and provides a distinct blue indication when the pilot is energized, making it ideal for status signaling in industrial control panels, machine dashboards, and electrical distribution enclosures. The 9001L31 is the blue color option in the 30 mm lens family and is commonly used to refresh worn or damaged lenses on 30 mm 9001K/9001SK modules, simplifying color-coded signaling across control panels. As a dedicated blue Fresnel lens for the 9001 pilot-light platform, it is listed under catalog number 9001L31 and is widely stocked by distributors alongside other lens colors for the same 30 mm module, helping maintain consistent visibility and reliability in panel indicators.
