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.
