Product Description
Cutler-Hammer
Purpose Contactors 15A through 360A,
from Eaton’s electrical business incor-
porate most competitive contactor
mounting dimensions into a single
baseplate. Contactors are dual-rated
with inductive and resistive ratings as
well as horsepower and kilowatt rat-
ings. C25 contactors are furnished with
pressure plates and quick connect ter-
minals as standard on 15, 25 and 30A
devices and with box lugs and quick-
connect terminals on 40, 50, 60 and
75A. Other terminal configurations are
available, see Table 14. Contactors will
accept add-on auxiliary contacts —
order factory assembled or as kits for
field installation.
The separately available snap-on
mechanical interlock permits interlock-
ing two contactors for reversing or
two-speed applications.
Contactors rated 15 – 50A only are
available with DIN rail mount as a fac-
tory installed option.
