■Relay (G2R-1A3-SN (SND), G2R-13-SN (SND))
Coil Ratings
Note: 1. The rated current and coil resistance are measured at a coil temperature of 23°C with a tolerance of +15%/–20% (AC rated current) or ±10%
(DC coil resistance).
2. LEDs are used for the built-in operation indicator. For models equipped with these indications, the VAC rated current must be increased
by approximately 1 mA; the VDC rated current, by approximately 4 mA.
3. Operating characteristics are measured at a coil temperature of 23°C.
