*1 Where 240VAC, the rated operational 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. Where 115VDC is indicated,
the current is set at 1 times making and 1 times breaking.
*2 The maximum making current complies with JIS C 4531, and enables 100 times
making at a power factor of PF: 0.7.
*3 The maximum breaking current, by referring to JIS C 4531, is based on
switching 25 times at PF: 0.4 (AC), time constant t = 100ms (DC) for either 115/230VDC
cases for the large capacity element. For the medium capacity element, switching 25 times
at PF: 0.4 (AC), time constant t = 40ms for 115VDC case only.
*4 The breaking time indicates the value when the coil is equipped with a
flywheel diode.
*5 In circuit with optcoupler, 5V 10mA can be used.
