Coil should not be pulsed with less than the nominal coil voltage and pulse width should be a minimum of three

times the specified operate time of the relay. If these conditions are not followed, it is possible for the relay to in

be the magnetically neutral position .

2.Switching voltage is for test purpose only and are no to be used as design criteria.
