NOTES 1. The range of coil current for AC relay is 15% (60 Hz). For DC relay it is 10% at 20C 68F. 2. The JA relay will operate in a range from 80% to 110% of the nominal coil voltage. It is however, recommended that the relay be used in the range of 85% to 110% of the nominal coil voltage, with the temporary voltage variation taken into consideration. 3. When the operating voltage of AC relays drops below 80% of the nominal coil voltage. The relay will generate a considerable amount of heat which is not recommended for maximum efficiency. 4. The coil resistance of DC types is the measured value of the coil at a temperature of 20C (68F). If the coil temperature changes by 1C. The measured value of the coil resistance should be increased or decreased by 0.4%. ADDITIONAL SERIES 1. Following up-graded contact rating types recognized by UL are available.
