Notes (1) Operating ambient temperature must consider "Must Operate Voltage Change Over Temperature," Contact Temperature Rise, Coil Temperature Rise (If coil is not allowed to cool) and Maximum Coil Temperature. Specification ambient considers nominal coil voltage, 20A load with coil cooled to ambient. (2) Sealed relay terminals should not be bent. (3) Knock-off nib should be removed after cleaning process for optimum life of sealed relays. (4) Maximum soldering temperature is 500F for 4 seconds. (5) Class F coils are UL systems approved for maximum coil temperature of 155C by change of resistance method. (6) See application note 13C265 for proper relay mounting, termination, cleaning and PC board conductor width. Coil rise test performed with 30A PC board to maintain 20C maximum rise @ 30A.
