Eaton E30EG 30.5 mm, Square Multifunction Pushbutton Operator

It carries NEMA 3, 3R, 4, 12 and 13 ratings, which covers rain and sleet outdoors, hosedown/watertight duty, and dust, dripping liquid and oil in industrial plants. That makes it suitable for an exterior enclosure door or a food plant washdown panel, provided the enclosure itself is rated to match.

Both buttons are momentary with interlock, top and bottom, so pressing one mechanically prevents the other from being actuated at the same time. That is what you want for a reversing application like a motor forward/reverse, a raise/lower, or an open/close, where energizing both directions at once would be a problem.

The light unit is 120 Vac and is an incandescent, transformer type, meaning the step-down transformer is part of the light unit itself. Feed it 120 Vac directly; no external control transformer is needed for the lamp.

Yes. The light unit will also accept an LED lamp, and the specified LED lamp number for this operator is 6PSB. Swapping to LED is the usual move on panels where relamping access is poor or the station runs lit continuously.

Use the interlocked two-button unit when the two commands must never be given together, such as forward/reverse or raise/lower, because the E30EG blocks simultaneous actuation of the top and bottom buttons mechanically rather than relying on contactor wiring alone. Two separate pushbuttons are the better choice when the functions are independent (start and a separate unrelated jog, for example) or when you need them spaced apart on the panel, since each takes its own 30.5 mm hole.

It is part of Eaton's E30 heavy duty 30.5 mm line, so it shares the same 30.5 mm mounting hole as the rest of the E30 operators, selector switches and pilot lights in that family. If your existing panel already uses E30 devices, this drops into the same cutout pattern and keeps the station appearance consistent.

Specify Eaton E30EG. It is an illuminated, two-button, 30.5 mm square multifunction operator in the E30 series, with momentary interlocked operation on both buttons.
