Note: 1. The figures for the rated current and coil resistance are for a coil temperature of 23 ° C and have a tolerance of ± 10%.
2. The figures for the operating characteristics are for a coil temperature of 23 ° C.
3. The figure for the maximum voltage is the maximum voltage that can be applied to the relay coil for period of 10 minutes at an ambient
temperature of 23 ° C. It does not apply to continuous operation.

The above values are initial values at an ambient temperature of 23 ° C unless otherwise specified.
The contact resistance was measured with 1 A at 5 VDC using the voltage drop method.
The insulation resistance was measured with a 500-VDC megohmmeter.
The impulse withstand voltage was measured with a JEC-212 (1981) standard impulse voltage waveform (1.2 × 50 μ s).
The mechanical endurance was measured at a switching frequency of 3,600 operations/hr.
The electrical endurance was measured at a switching frequency of 60 operations/hr.
