Notes:
#1
This value can change due to the switching frequency, environmental conditions,
and desired reliability level, therefore it is recommended to check this with the
actual load.
When using a surge absorbing element for the relay coil drive circuit, please use
with a surge absorbing element with a clamp voltage of 1.5 to 2.0 times the rated
operating voltage. When the coil is connected in parallel with a diode, resistor or
capacitor, the release time will delay which might lead to degradation in shutoff
performance and electrical life.

Contact terminals have polarity; therefore, please obey the wiring diagram when
connecting contacts.
The electrical load performance value applies when a varistor is connected in
parallel with the coil.
