Answer:
Yes, but you will only use one of the three phases to run the single phase device. You also have to make sure the voltage and current rating is current.
Another, more detailed answer:
Yes, you can use one of the three phase service lines to run the single phase device. However, before you connect it, you must first make sure that both the voltage and the current rating of the device will be suitable for the single phase service that your new connections to the service wiring will produce.
The single phase voltage you will get between any one phase line and the neutral point is less than the voltage between any two of the three phase service lines by a factor of 1/1.73. So, because 415/1.73 is about 240, a 415V 3-phase service will produce a single phase voltage of 240V.
If you are in one of the many countries which use split single phase wiring - such as USA and Canada - that 240V will actually be available as two 120V "hots" (usually with red and black colored insulation) balanced about the neutral point i.e. +120V / Neutral / -120V.
Thus you can actually connect up a new branch circuit either for one 240V single phase device or two 120V branch circuits to supply power to 120V devices.
After you have made sure that the current demanded by your single phase device can be supplied by the available 3-phase service, it is vital that you make sure you install the correct size of circuit breaker (voltage and ampacity) and branch circuit wiring having the correct wire size to carry the current load drawn by the single phase device, together with the correct types and sizes of socket outlets. All these details are specified in your country's national electrical codes or regulations.
(1.73 is the square root of 3).

As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.
Before you do any work yourself,
on electrical circuits, equipment or appliances,
always use a test meter to ensure the circuit is, in fact, de-energized.
