ABB AF12-30-10-12 Contactor

The ABB AF12-30-10-12 Contactor is a three-pole, AF12-series control relay designed for panel-mounted motor control and general-purpose switching in industrial automation. It provides three main contacts and a single normally open auxiliary contact, enabling simple interlocking and status signaling within control circuits. The coil is designed for universal drive in the 48–130 VAC or DC range, with 50/60 Hz compatibility, allowing reliable operation from typical industrial control power supplies without coil changes. This model, identified by the AF12-30-10-12 designation, is sized for medium-duty loads within ABB’s AF12 family and is commonly used to start and stop three-phase motors, pumps, fans, and conveyors in manufacturing environments. The AF12 line is recognized for compact footprint and fast response, offering dependable switching for control panels and equipment where compact, one-package contactors are preferred. For design and replacement planning, this exact variant ensures compatibility with other AF12 devices and ABB’s catalog ecosystem, simplifying stocking and wiring schemes in multi-contactor layouts.
