1. The figures in winding capacity and minimum fall load are obtained with the use of 8B drum .
  2. "a/b" in speed and full-load current are measured under the 50Hz; "a" and 60Hz; "b" power respectively.
  3. Use environment : Ambient temperature; -10℃ to +40℃ (subject to no freezing ・dew condensation). Ambient humidity less than 85%RH.
  4. Time rating is the value measured at +20℃. If the temperature exceeds this value, the time rating gets shorter.
  5. Durability : 10,000 opening and closing
  6. It is available to produce the operator with different operating voltage except.
