Inrush Current Resistance: Non-repetitive
Keep the inrush current to below the inrush current resistance value (i.e., below the broken line) if it occurs repetitively.

Note: If a commercially available heat sink is used, use one that has
a heat resistance equal to or lower than a standard OMRON
Heat Sink.

Note: The heat sink area is the combined
area of all surfaces of the heat sink
that radiate heat.
For the G3PE-525B-3H, when a
current of 18 A flows through the SSR
at 40°C, the graph shows that a heat
sink area of about 2,500 cm
be required. Therefore, if the heat
sink is square, one side of an
aluminum plate in the heat sink must
be 36 cm or longer (√2,500 (cm
36 cm (rounded to a whole number)).
