Allen-Bradley 100-A45N3 Contactor

Allen‑Bradley 100-A45N3 Contactor is a three‑pole motor starter rated for 45 A and designed for industrial control of three‑phase motors and similar inductive loads. The coil operates at 110/120 VAC for 50/60 Hz control circuits, enabling direct interfacing with standard plant controls, while the load side is rated to switch up to 600 VAC, accommodating common motor voltages in manufacturing environments. Optional auxiliary contact blocks—such as the 195-GA10—can be added to extend signaling or interlocking capability without replacing the base unit. Typical applications include conveyors, pumps, fans, and other mid‑range motor control tasks where dependable switching and straightforward replacement in legacy Allen‑Bradley systems are important. As a member of Allen‑Bradley’s Bulletin 100 family, the 100‑A45N3 shares mounting compatibility and accessory options with other 100‑series contactors, providing a consistent, widely available solution for panel builders and maintenance teams.
