The figures in winding capacity and minimum fall load are obtained with the use of 5B drum at single-phase 100V or 6B drum at three-phase 200V.

"a/b" in speed and full-load current are measured under the 50Hz; "a" and 60Hz; "b" power respectively.

Use environment: Ambient temperature; -10℃ to +40℃ (subject to no freezing・dew condensation). Ambient humidity less than 85%RH.

Time rating is the value measured at +20℃. If the temperature exceeds this value, the time rating gets shorter.

Shutter shall be surely equipped with the emergency limit switch.

Durability: 10,000 opening and closing

It is available to produce the operator with different operating voltage except.
