Note: Ratings and specifications are defined according to IEC 62246-1.
*1. Rated insulation voltage is the voltage value which is the standard of insulation design and defined by the withstand voltage test.
*2. Rated continuous current is the current value which can be energized continuously without exceeding the allowable temperature rise under
   the condition without breaking contacts.
*3. Rated operational current is the current value which is combined with a rated operational voltage and used in regulated conditions
   (making/breaking current, switching frequency and electric switching durability).
   At 240VAC, the current is set at 10 times this value upon making (PF: 0.6 to 0.7) and 1 times this value upon breaking (PF: 0.3 to 0.4).
   Rated operational current 1A means 10A making and 1A breaking. At 115VDC, the current is set at 1 times making and 1times breaking
   and indicated by inductive load (L/R=40ms and 100ms).
*4. Maximum making current is the current value which enables 10 times making at 240VAC and PF: 0.3 to 0.4 by referring to IEC 62246-1-1.
*5. Maximum breaking current is the current value which enables 10 times breaking at 240VAC and PF: 0.3 to 0.4 by referring to IEC 62246-1-1.
*6. Minimum operational power ratings are the values which can be surely energized under the regulated load conditions that the class of
   contact reliability keeps a failure rate 0.005 (time/10⁶) or less.
