ABB / AF Contactors
ABB AF400-30-11 3-Pole Contactor
Three-pole contactor with three normally open main contacts and one normally open plus one normally closed auxiliary contact.
Product Overview
High-current three-pole switching with electronic coil technology
ABB AF400-30-11 is the base designation for a three-pole AF contactor. Common contact data include three normally open main contacts and integrated 1 NO + 1 NC auxiliary contacts.
Official coil variants use different suffixes and control-voltage ranges. Because the requested model omits that suffix, this page does not assign a coil voltage; procurement must verify the complete order code.
