-4 Relay (5 amps max coil rating)
Multi-pole units with mixed construction, poles numbered
left to right when viewed from terminal end (Note F).
For addition of inertial delay, add an “ F ” to any delay
number. Except 40, 50 & 60.
*Instantaneous delays are not compatible with
inrush enhancement options and are not recommended
for general use.
See page 61 for maximum voltage ratings.
Note: Standard current ratings listed.
For other ratings, please consult the factory.
