The rated current and coil resistance are measured at a coil temperature of 23°C with a tolerance of
±
10%.
The operating characteristics are measured at a coil temperature of 23°C unless otherwise specified.
Pick-up voltage will vary with temperature
The maximum voltage is the highest voltage that can be imposed on the relay coil instantaneously.

The contact resistance was measured with 10 mA at 1 VDC with a voltage-drop method.
Values in parentheses are typical values unless otherwise stated.
The insulation resistance was measured with a 500-VDC megohmmeter applied to the same parts as those for checking the dielectric strength.
Data shown are of initial value.
