In a word - No!

You need a 'soft start' Modern ones comprise a Silicon Controlled Rectifier in series with the load, and it's triggering phase angle starts at 180 and progressively advances to 0 degrees.

More old fashioned ones comprise a power resistor with a relay contact across it. A second or so after power is applied the relay triggers shorting out the relay resistor.
