Specifications

Coil Rating

Note: 1. The rated current for AC is the value measured with a DC ammeter in half-wave rectification.

2. 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.

3. The AC coil resistance is a reference value only.

4. Operating characteristics were measured at a coil temperature of 23°C.

5. The maximum voltage capacity was measured at an ambient temperature of 23°C.

Contact Ratings

* With no icing or condensation.

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.

*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.
