Description
Fuji Electric SC14AA SC-05 Non-Reversing AC Contactor 3-Pole 20A 5HP 100V Coil
The Fuji Electric SC14AA is a 3-pole, non-reversing AC contactor in the SC-05 frame size, designed for motor starting and switching applications in industrial control panels. It operates on a 100-110V AC, 60Hz control coil and handles line voltages from 200V through 600V, making it suited to both North American and international three-phase power systems. The contactor includes two normally-open (2NO) auxiliary contacts for control circuit interlocking and status signaling.

Applications
AC contactors in the SC-05 class are standard components in three-phase motor control centers, machine tool panels, pump control circuits, conveyor systems, and HVAC equipment. The SC-05 is an IEC-rated frame size commonly used across Europe, Asia, and in IEC-standard industrial facilities worldwide, controlling motors in the 3-5 HP range at typical industrial voltages. Non-reversing contactors like this one are used for across-the-line motor starting where the motor runs in only one direction. The 2NO auxiliary contacts allow interlocking with a control PLC, relay logic, or indicator circuits — a common requirement in automated machine control. Fuji Electric has been a major producer of industrial electrical control components since the mid-twentieth century, and their SC-series contactors have been widely specified in Japanese-manufactured machinery exported globally. The lot code 8420 suggests this unit dates from the mid-1980s, placing it in the era when IEC-standard contactors were displacing earlier NEMA-style designs in international industrial equipment.
This Fuji Electric SC14AA SC-05 Non-Reversing AC Contactor was pulled from a working industrial environment where it had been in service. It has been visually inspected and photographed. The housing and terminal blocks appear to be in good used condition with normal wear consistent with industrial service — some light surface marks on the body are visible, but the contact blocks, terminal screws, and auxiliary contact assembly all appear intact. The orange rating label and coil identification label are present and legible. Cosmetic wear is typical for surplus industrial contactors of this type. Please review all photos carefully and contact us with any questions before purchasing.
