It is recommended to test actual load conditions for the application. It is the user’s responsibility to determine the performance suitability for their specific application. The use of any coil voltage less than the rated coil voltage may compromise the operation of the relay. www.citrelay.com phone - 763.535.2339 Dimensions shown in mm.
