When using B-series (screw) products, since the screw diameter of the contact terminal is M4, be careful that the contact current should be 20 A or less
according to JET standard (electrical appliance and material control law of Japan).

Note: 1.
The ratio of rated voltage between 100 to 120 VAC are values
measured on the basis of 100 VAC
2.
When driving a transistor, check the leakage current and connect
a bleeder resistor if necessary.
3.
The AC coil is provided with a built-in full-wave rectifier. If a triac,
such as an SSR, drives the G7L, the G7L may not release. Be sure
to perform a trial operation with the G7L and the triac before ap-
plying them to actual use.

Note: 1.
The rated current and coil resistance are measured at a coil temperature of 23°C with tolerances of +15%/-20% for AC rated current and
±15%
for DC coil resistance.
2.
The inductances shown above are reference values.
3.
Performance characteristic data are measured at a coil temperature of 23°C.
4.
The maximum allowable coil voltage refers to the maximum value in a varying range of operating power voltage, measured at ambient
temperature 23°C.
5.
The “to” (for example “100 to 120”) represents a range of rated voltages.
