Fuji Electric Terminal Cover for use with SZ-HB

This unit counts the ON-OFF operation times of a contactor. The contact lifetime can be estimated at a glance. This operation counter unit is a mechanical type counter which can be easily attached to the SC series contactors (Frame size 03 to N3) with snap-on fittings. Before, the operation times of contactors were estimated from the operation status of other equipment. However, the operation times of contactors can be precisely counted and easily checked with this unit. The date for periodical maintenance and contact lifetime can be estimated directly counting the operation times of Contactors.
