The figures in the winding capacity and minimum fall load are obtained with the use of 4B drum. When the 5B drum is used, the winding capacity is reduced to 0.85 time from the above ratings.

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

The single-phase except 100V corresponds to 220V power, whereas the three-phase except 200V to 400V power (Full-load current is chageable by individual voltage).

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.
