That seems overly pessimistic?
The data sheet for this particular relay only has a resistive rating, however looking at another relay with similar resistive rating that does provide an inductive switching rating, see below and appears to be capable of switching about 3A @125Vac Cos Φ = 0.4, 500,000 operations.
I looked at several contact curves and the rule of thumb seems to be about 1/2 rated (voltage and current) for Cos Φ = 0.4 or in some cases just 1/2 rated voltage for inductive load.
