30 mm Blue Fresnel Pilot Lens

This 30 mm blue pilot light lens is made of plastic with a Fresnel surface for even illumination. It is designed for use with Pres-Test lights and illuminated push buttons in industrial control panels. The component carries NEMA ratings 1, 2, 3, 3R, 4, 4X, 12 and 13 alongside an IP66 rating. It is also CSA certified and UL Listed for compliance.

Mounting and Panel Integration

The lens fits a standard 30 mm cut-out and threads into compatible Eaton pilot light or push button bodies. Its plastic construction resists corrosion and suits indoor or outdoor enclosures meeting the listed NEMA types. The IP66 rating confirms protection against powerful water jets and dust ingress. No additional sealing hardware is required when installed correctly.

Included Certification and Compliance

The product ships as a single lens without mounting hardware or wiring accessories. Its value lies in the pre-verified NEMA and IP ratings that simplify panel certification. CSA and UL listings reduce the documentation burden for control panel builders. Buyers needing different colours, lens profiles or legend plates must source those separately.

Questions about this item

What NEMA ratings does the 30 mm blue lens cover for sustained industrial use?

The lens is rated for NEMA 1, 2, 3, 3R, 4, 4X, 12 and 13 enclosures, so it withstands dust, water jets and corrosion in continuous service.

How much heat or noise does the plastic lens add when the pilot light runs all day?

The lens itself is passive plastic; it generates no heat or noise, and the Fresnel design does not change the lamp’s thermal output.

Which Eaton Pres-Test or illuminated push-button series must I already have for this 30 mm lens to fit?

It fits any Eaton 30 mm Pres-Test pilot light or illuminated push button that accepts a snap-in Fresnel lens.
