Note:
1. The contact performance specifications refer to the built-in contacts.
2. The rated operational current indicates the current value to be used under the rated operational voltage and specified conditions (make and break current, switching frequency, and electrical endurance).
For 240VAC: The setting is based on 10× make (cosφ = 0.6–0.7) and 1× break (cosφ = 0.3–0.4). A rated operational current of 1A means 10A for making and 1A for breaking. For 115VDC: The setting is based on 1× make and 1× break, specified for inductive loads (L/R = 100ms).
3. The operating time of NO contact and NC contact may overlap.
4. Time characteristics are values measured at an ambient temperature of +20℃ with the coil energized at its rated voltage.
5. Values of vibration/shock resistance are with vibration-proof band attached.
6. Temperature characteristics are values under conditions without freezing or condensation.

Note:
1. Maximum allowable voltage is the maximum value that can be applied to the coil in consideration of its thermal degradation and insulators in the relays. This is not a continuous allowable voltage.
2. For rated voltage DC, operating voltage is 72%E or less for contact a, 82%E or less for contact b, and 10%E or more for releasing voltage.
3. For rated voltage AC, operating voltage is 68%E or less for contact a, 82%E or less for contact b, and 15%E or more for releasing voltage.
