Allen-Bradley 100-A75N3 Industrial Power Contactor

Allen-Bradley 100-A75N3 is a three-pole magnetic power contactor used to switch heavy electrical loads in industrial control panels. The model designation identifies a 100-A series device with a 75-amp rating, designed for robust, repeated operation in motor control and equipment start/stop circuits. As part of the 100-A family, this contactor is built to withstand demanding industrial environments and to work with standard auxiliary components and control logic common in industrial automation systems. Designed for panel mounting, it accepts fast, secure mounting within enclosed control cabinets and gear racks. Applications include starting and stopping motors on conveyors, pumps, fans, and other mechanical systems, as well as switching other inductive or resistive loads where reliable, high-current switching is required. The Ser C configuration indicates a defined set of companion parts and accessories compatible with this variant, helping integrators match interlocks, auxiliary contacts, and mechanical latching options to the control scheme. When selecting exact specifications for replacement or integration—such as coil voltage, contact arrangement (number of normally open/closed contacts), and available auxiliary contacts—consult the catalog listing for 100-A75N3 Ser C to ensure compatibility with your electrical design, safety standards, and panel density constraints.
