1/ CAUTION: Compare with time current characteristics of the associated
circuit protective device.
2/ ALL relays shall withstand overload and fault currents. Relays must be
able to sustain five applications (make and carry only) of power
concurrently on adjacent poles at each of four different current levels in
the sequence listed in table I. Separate relays shall be tested at 28 V
dc and 115/200 V ac, 400 Hz, 3 phase. Cooling time between
successive applications shall be 30 minutes. Tests shall be performed
on both normally applications shall be 30 minutes. Tests shall be
performed on both normally open and normally closed contacts. There
shall be no failures or evidence of open and normally closed contacts.
There shall be no failures or evidence of open and normally closed
contacts. There shall be no failures or evidence of open and normally
closed contacts. There shall be no failures or evidence of welding or
sticking and relays shall pass contact voltage drop at the conclusion.
COIL DATA 4/: (See table II.)
Operate time: 4 milliseconds maximum with rated coil voltage.
Duty rating: Continuous.
ELECTRICAL DATA:
Insulation resistance, initial: 100 megohms.
After life or environmental tests: 50 megohms.
________
4/ CAUTION: Due to possible interaction of relay magnetic fields, the following spacing requirements, as a
minimum, shall be considered in dense packaging situations:
a. Row to row assisting fields: .125 inch.
b. Row to row opposing fields: .1875 inch.
c. Side to side alternating fields: .0625 inch.
d. Side to side like fields: .125 inch.
5/ Dielectric may be improved by suitable insulation of terminals and wiring after installation.
