Coil Ratings
Note: 1.
For AC models, the rated current values are half-wave rectified current values measured with a DC ammeter.
2.
The rated current and coil resistance are measured at a coil temperature of 23
°
C with tolerances of +15%/–20% for AC rated current and
±
15% for DC rated current, and +15% for DC coil resistance.
3.
The AC coil resistance values are for reference only.
4.
Performance characteristic data are measured at a coil temperature of 5
°
C to 35
°
C.
