What the Description Tells You
The A16-04-10-84 is a 4-pole contactor (4P CONTR) with 4NC auxiliary contacts. The '4NC' means all four auxiliary poles are normally-closed — unusual for a general-purpose contactor, which typically mixes NO and NC. This configuration suits applications where the contactor must fail to a closed state on the auxiliary side, or where the control logic requires all NC feedback for a safety or interlock circuit. The 4-pole main contacts handle three-phase power plus a neutral or fourth pole for two-speed motor wiring.
