4 NC Contacts Auxiliary Contact. Not available new because these 100S-FA & 100S-FB aux contacts are used on the 100S-C safety contactors and must be assembled on the contactor at the factory. Factory won’t allow customer to order to build a safety contactor and if the aux contact goes bad; entire contactor must be replaced. Both the standard cross stamped aux contact block and bifurcated aux contact blocks are labeled 100S-F on the side of the red block. To determine if the aux conatct block is standard or bifurcated look at the top surface of the contact block in the lower left corner. A or B + 2 digits = standard aux contact block AB or BB + 2 digits = bifurcated aux contact block
