ABB AF40-30-00-11 Contactor is a three-pole, DIN-rail-mountable device designed to switch three-phase loads with a main-contact rating up to 690 V and 40 A. It uses a 3PST-NO configuration (three-pole, single-throw, normally open) for standard on/off control in motor starters, pumps, fans, and other automation applications in control panels. The coil accepts 24–60 V AC (50/60 Hz) or 20–60 V DC, enabling flexible control from common PLC outputs and DC control circuits. As part of ABB’s AF40 family, this contactor is intended for DIN-rail mounting in standard electrical enclosures, delivering reliable switching for industrial automation environments.
