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).
*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 PAS 62246-2-1.
*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 PAS 62246-2-1.
*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. In circuit with photo coupler, 5V 10mA can be used for digital application.
