Note: Use a varistor as a protective circuit against reverse surge connected parallel to the coil. The reverse blocking voltage
should be about 3 times the value of the power source voltage.
* Minimum switching loads mentioned above are reference values. Please perform the confirmation test with actual
load before production since reference values may vary according to switching frequencies, environmental conditions
and expected reliability levels.

Note 1: All values in the tables are valid for 20°C and zero contact current.
Note 2: Nominal voltage is different from indication of part number. Please refer to the coil rating
chart "single coil (10A, 200VDC configuration)" for single coil configuration data.
Note 3: Please use with nominal voltage. When energizing higher voltage to coil, please refer to
characteristic data "coil temperature rise" and "operating range" (page 4) to set suitable voltage.
* Specified operate values are valid for pulse wave voltage.
