The rated current and coil resistance are measured at a coil temperature of 23°C with a tolerance of
±10%.
Operating characteristics are measured at a coil temperature of 23°C with a tolerance of
±10%.
The maximum voltage is the highest voltage that can be imposed on the relay coil.
The maximum voltage that can be be applied when using the G6H-2F (at 85°C) is 115% (3 to 12 V) or 105% (24 V) of the rated voltage.

Insulation resistance (See note 3)
Dielectric strength
Note: 1.
The contact resistance was measured with 10 mA at 1 VDC with a fall-of-potential method.
2.
Values in parentheses are typical values unless otherwise stated.
3.
The insulation resistance was measured with a 500-VDC megohmmeter applied to the same parts as those for checking the dielectric strength.
(The insulation resistance between the set and reset coil (G6HK-2), however, is 100MΩ min. when measured with a 125-VDC megohmmeter).
4.
The above values are initial values.
