Eaton E34TPB480 – Frequently Asked Questions

1) Will an Eaton E34 pilot light hold up in a washdown or outdoor panel?
Yes. The Eaton E34 indicating light is built as a 30.5 mm corrosion-resistant watertight/oiltight unit and carries NEMA 3, 3R, 3S, 4, 4X, 12 and 13 ratings, so it covers rain and outdoor exposure (3, 3R, 3S), hosedown and corrosive washdown (4, 4X), and oil or coolant splash inside a machine enclosure (12, 13). It is also UL Listed.
2) What panel hole size does the Eaton E34 indicating light mount in?
It is a 30.5 mm device, which is the standard heavy-duty control panel cutout used for industrial pushbuttons and pilot lights. If your existing station is punched for 30.5 mm operators, this drops into the same hole.
3) What voltage control circuit is this Eaton pilot light rated for?
480 V. It is intended for industrial control circuits at that rating, which is why the light unit is the transformer type rather than a direct-voltage lamp.
4) Can I test the lamp on this Eaton pilot light without pulling the lens?
Yes, that is what the PresTest actuator does. You press the lens cap in place and the lamp lights, so a technician can confirm a burned-out bulb during a walkdown without opening the enclosure or removing the cap.
5) Is the Eaton E34 indicating light LED or incandescent?
Incandescent, transformer type. The transformer steps the control voltage down to the lamp, so the replacement bulb is a low-voltage incandescent rather than a full-line-voltage lamp. If your maintenance standard has moved to LED lamp units, this is not that device.
6) Which Eaton E34 part numbers should I order?
Two catalog numbers cover this indicating light: E34TPB240 and E34TPB480. Quote the full number on your order, since the trailing digits are what separate the two.
7) Will this pilot light survive direct sunlight on an outdoor control station?
Where the device sees ultraviolet light, Eaton's own guidance is to pair it with NEMA 4X 10250T operators for longer service life. Plan the station that way for rooftop, yard, or south-facing outdoor mounting rather than relying on the E34 unit alone under constant UV.
8) Is this indicating light suitable for a food plant or chemical area panel that gets hosed down?
Yes. The NEMA 4X rating covers hosedown plus corrosion resistance, and 12/13 cover oil and coolant ingress, which is the combination facility and MRO buyers usually specify for washdown production areas and chemical handling rooms. It is UL Listed for use in commercial and industrial electrical systems.
