COIL DATA
Non-latching – AC
Note: 1. The rated current and coil resistance are measured at a coil temperature of 23°C (73°F) with tolerances of +15%, -20% for
AC rated current, and ±15% for DC rated coil resistance.
2. The AC coil resistance and inductance are reference values at 60 Hz.
3. The performance characteristics are measured at a coil temperature of 23°C (73°F).
4. Because the coil is designed for low power consumption, connect a bleeder (if necessary after confirming the leakage
current), when the coil is driven by an SCR.
5. For AC type latching coils, the rated current values are half-wave rectified current values measured with a DC ammeter.
