The number plate doesn't say, but I'd be willing to bet that the 1700 watts connection is for 20 amp 110 volt circuits only.
1700/110=15.45 amps. This is within the 20% margin of error normally allotted to such circuits. In other words, on a 20 amp circuit, 16 amps maximum would be allowed.
On a 15 amp circuit, 12 amps or 1320 watts would be the 80%maximum for any single appliance. Some appliances may say they draw 1500 watts but that is usually an overstatement or the maximum on startup - a temporary draw. For example, I just bought a small all-metal "utility heater" for sticking under my desk at the shop. The tag says it's 1500 watts. But I stuck it on a watt meter on high and it draws just a little over 1300 watts.
This is probably also why 110 volt American front loaders' heating elements are generally limited to 1000 watts - any more would mean that the motor would not be allowed to come on during heating (as is or was the case with the heated Speed Queen front loader) because that would cause the appliance to exceed the 80% safety figure.
