Liquid Drainage
Eaton’s Cutler-Hammer pushbutton
operators offer front of panel drainage
via holes in the operator bushing. Hid-
den 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 wash-
downs, effectively relieving pressure
from the internal diaphragm seal,
ensuring reliable sealing in applica-
tions even beyond NEMA 4.

10250T Grounding
10250T line operators have “grounding
nibs” — four metal points on the oper-
ator casting designed to bite through
most paints and other coatings on
metal panels to enhance the grounding
connection when the operator is
securely tightened.

E34 Grounding
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 enclo-
sure and eliminates the need for extra
kits when daisy chain grounding is
required.
