All 10250T contact blocks shown are suitable
for use on standard 10250T and E34 opera-
tors. These contact blocks are not suitable for
Class I Division 2 type 10250T or E34 devices.
Contact blocks with spade terminals are lim-
ited to a maximum of one contact block per
operator and minimum spacing between
devices is 2.5” (63.5 mm). Not suitable for
use in 10250T or E34 enclosures. Also avail-
able in amber housing. Not available with
fingerproof shrouds.

Reliability Nibs
Reliability nibs are the hallmark of
Eaton’s Cutler-Hammer contact blocks.
A pointed silver nib on the contact tip
ensures reliable switching from logic
level (5V) up to 600V applications.

Special function contact blocks are not suit-
able for use with roto-push operators, 3-
position push-pull operators, or 4-position
selector switches.
ECNO contact blocks are not suitable for use
with 2-position joysticks or when operators
are used with padlock attachments.

Therefore standard contact blocks can
be used for most logic level applica-
tions where the contacts are not
exposed to any harsh environmental
conditions.
Palladium Contacts
Palladium, which is more inert than
gold, is well suited for voltages and
currents approaching zero and is rec-
ommended for applications where
environmental conditions are a factor.

Operators
Special purpose 10250T44 contact blocks
are not suitable on selector switches or roto-

push-pull operators only on low voltage
(30V or less) circuits. Fingerproof shrouds
not available.
