Allen-Bradley 100-A45NZ243 DC Coil Magnetic Contactor

Allen-Bradley 100-A45NZ243 is a three-pole DC coil magnetic contactor with a 24 VDC control coil, designed to switch three-phase power for motors and other inductive loads in industrial control systems. This model carries a 45 A load current rating and is part of the 100-A family of DC-coil contactors, known for compact, rugged control of mid-range motors. When paired with standard line voltages, the contactor supports motor horsepower ranges of up to 3 HP at 115 V (1-phase), 7.5 HP at 230 V (1-phase), 15 HP at 230 V (3-phase), 30 HP at 460 V (3-phase), and 40 HP at 575 V (3-phase), illustrating its versatility across common industrial applications. The DC24V coil version is suitable for control schemes that provide a 24 VDC signal, enabling reliable energization and switching of the load with a 3-pole configuration. Typical use cases include conveyors, pumps, fans, and other equipment requiring dependable remote motor control in automation environments. The exact configuration is identified by the 100-A45NZ243 part number, which denotes a 3-pole, 45 A DC-coil contactor designed for integration into standard Allen-Bradley control circuits.
