The General Electric CR120BD Series A in-
dustrial relay is the de form of the stan-
dard CR120B relay. This de relay is fur-
nished with a dual winding coil and a
special contact is suppited in the coil cir-
cuit to make available the higher current
needed during the first part of the arm-
ature stroke. This contact should be re.
placed only with a CR120BX1A contact
module. Because of the higher watts used
during pickup, the relay should not be
operated continuously more than 80 oper-
ations per minute.
The CR120BC catalog numbers designate
the latch forms of the dc relay. Since
these relays have an intermittent rating on
the unlatch coil it should be limited to a 25
percent duty cycle.
