Ratings and Specifications
Ratings
Operating Coil
Note: 1. The rated current and coil resistance are measured at a coil temperature of 23°C with tolerances of +15%/−20% for the AC rated current and ±15% for the
DC coil resistance.
2. The AC coil resistance and inductance values are reference values only
3. Operating characteristics were measured at a coil temperature of 23°C.
4. The maximum voltage capacity was measured at an ambient temperature of 23°C.
*1. There is variation between products, but actual values are 80% max.
To ensure operation, apply at least 80% of the rated value
*2. There is variation between products, but actual values are 30% minimum for AC and 10% minimum for DC. To ensure release, use a value that is lower than the
specified value.
Contact Ratings
Characteristics
Note:
The above values are initial values.
*1.
Measurement conditions: 1 A at 5 VDC using the voltage drop method
*2.
Measurement conditions: With rated operating power applied, not including contact bounce.
Ambient temperature condition: 23° C
*3.
Measurement conditions: For 500 VDC applied to the same location as for dielectric strength
measurement.
*4.
Ambient temperature condition: 23° C
*5.
This value was measured at a switching frequency of 120 operations per minute.
