Selection criteria
Check the load type, rated operational current, motor power and operating voltage. Specify the coil voltage and frequency, required auxiliary contacts and any overload relay or interlock. The AC-3 power rating alone does not establish suitability for every switching duty.
For control circuits, see Iskra AC contactor relays. For accessories, see auxiliary contact blocks and overload relays.
Contact Appel with the type designation and application details for product selection.
