General-purpose Relay LY A-33
Electromechanical
Relays
Three-pole Relays
Note: See notes under next table.
Four-pole Relays
Note: 1. The rated current and coil resistance are measured at a coil temperature of 23°C with tolerances of +15%/–20% for rated currents and
±15% for DC coil resistance.
2. Performance characteristic data are measured at a coil temperatures of 23°C.
3. AC coil resistance and impedance are provided as reference values (at 60 Hz).
4. Power consumption drop was measured for the above data. When driving transistors, check leakage current and connect a bleeder re-
sistor if required.
