NOTES:
Coil should not be pulsed with less than the rated coil voltage and the pulse width should be a minimum of three times the spec-
ified operate time. If not, it is possible for the relay to settle in a magnetically neutral position.
Must Operate Voltage is listed for test purposes only and is not to be used as design criteria.
