Allen-Bradley 100-A30NA3 Contactor

Allen-Bradley 100-A30NA3 is a three-pole motor-contactor designed to switch up to 30 A for three-phase loads, with a maximum switched voltage of 600 V AC. The coil operates at 220 VAC, enabling control from standard low-voltage control circuits in industrial panels. Three main contacts are rated for 30 A, supporting reliable switching of motor loads while the coil energizes to close the contacts. This unit is used in industrial control panels to start and run three-phase motors and other high-current loads, offering a compact, open-frame design compatible with common panel mounting schemes. Manufactured by Allen-Bradley (Rockwell Automation), this part belongs to the 100-series family of contactors and is commonly found in replacement and retrofit scenarios for older equipment. Typical applications include conveyors, pumps, fans, compressors, and other machinery where remote motor starting with robust current handling is required.
