Specifications
■
Coil Ratings
Note: 1.
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 coil resistance. (The values given for AC rated current apply at 50 Hz or 60 Hz.)
2.
Performance characteristic data are measured at a coil temperature of 23
°
C.
3.
The maximum voltage is one that is applicable to the Relay coil at 23
°
C.
■
Contact Ratings
Note:
The values in parentheses indicate values for a bifurcated contact.
