Every voltage has two official levels; a "distribution voltage" and a "utilization voltage". The distribution voltage is what the utility supplies at your service drop, i.e. 480, 240, 120 etc. The utilization voltage is the voltage level to which the end use equipment is manufactured, which is purposefully lower to allow for expected voltage drop from the utility connection point to the end device due to wire length. So for 480V distribution, motors are made for 460V utilization, 240V becomes 230V, 120V becomes 115V and 208V becomes 200V. Nobody uses 201V, it's most likely a typo, rounding error or it's something from a place like China where the mfr has no clue what they are doing because they don't engineer anything, they just copy something else and they wrote down the numbers wrong when they copied it.
