Allen-Bradley 100-C72D10 Industrial Magnetic Contactor

Manufactured by Allen-Bradley (Rockwell Automation), the 100-C72D10 is a three-pole electromagnetic contactor rated for 72 A, built to switch motors, heaters, and other heavy loads in industrial control systems. It uses a 120 V AC coil and heavy-duty power contacts, and is panel- or DIN-rail mountable depending on the installation. This device is commonly installed in motor control centers, starter panels, conveyor systems, and automated machinery where frequent and dependable contact switching is required, and it is intended for industrial control circuits in industrial electrical systems. End users such as maintenance teams, OEM engineers, and system integrators rely on it for control panel builds, upgrades, retrofits, or replacement of worn contactor devices. Common replacements include Allen-Bradley 100-C72EJ10, Eaton DILM65-10, and Siemens 3RT1045 contactors.
