Allen-Bradley 74A83 is a 240V AC coil designed for use with Bulletin 700 series contactors, specifically Series K, Size 4, to energize 2- to 3-pole motor starters in industrial control circuits. The coil operates on 240V AC at 60 Hz (with 220V/50 Hz variants available in other markets), enabling standard North American control systems. It supports a range of starter configurations, including non-reversing, reversing, and multi-speed setups, when paired with compatible 700-series contactors. This USNT-rated coil is intended to provide reliable electromagnetic actuation for motor control applications across demanding industrial environments.
