Pushbuttons and Indicating Lights
30.5 mm Class I Division 2 Hazardous Locations—10250T/E34
Product Overview
Operator
The 30.5 mm 10250T
pushbutton line features a
zinc die cast construction with
chrome-plated housing and
mounting nut.
Eaton’s E34 Series 30.5 mm
pushbutton line features the
same rugged die cast
construction of our 10250T
line with an additional two-
layer 100% solid thermosetting
cathodic epoxy coating. This
coating provides a flat black
smooth, consistent, corrosion
resistant surface that has
passed a demanding 600 hour
salt spray test. (The industry
standard for this 4X test
requires only 200 hours.)
Ultraviolet Light
E34 epoxy coating is not
recommended for use in
applications where exposure
to ultraviolet light exists—use
NEMA 4X 10250T operators.
Ratings
Our Class I Division 2 line of
pushbuttons are UL Listed
(NEMA type) 1, 2, 3, 3R, 4,
4X, 12 and 13. Our Class I
Division 2 E34 line meets IEC
947-1 IP66 standards and the
cathodic coating meets FDA
3A sanitary chemical
resistance requirements.
For a complete listing of all
applicable ratings see
Pages V7-T1-357 to
V7-T1-358.
10250T Grounding Nibs
10250T line operators have
“grounding nibs”—four metal
points on the operator casting
designed to bite through
most paints and other
coatings on metal panels to
enhance the grounding
connection when the
operator is securely
tightened.
10250T Grounding Nibs
E34 Grounding Nibs
E34 line of operators is
equipped with a ground
screw terminal as part of its
die cast construction. This
earthing terminal provides an
easily accessible point for
grounding operators when
used in a painted or
nonmetallic enclosure and
eliminates the need for extra
kits when daisy chain
grounding is required.

Diaphragm Seal with
Drainage Holes
Liquid Drainage
Eaton’s pushbutton operators
offer front of panel drainage
via holes in the operator
bushing. Hidden from view by
the mounting nut, these
holes prevent buildup of liquid
inside the operator, which
can prevent operation in
freezing environments. The
holes also provide a route for
escaping liquid in high
pressure washdowns,
effectively relieving pressure
from the internal diaphragm
seal, ensuring reliable sealing
in applications even beyond
NEMA 4.
