Description
Fuji Electric SC18AG SC-4-0/G Non-Reversing Contactor 24VDC Coil 25A AC3
The Fuji Electric SC18AG is a non-reversing IEC-style AC contactor in the SC-4-0/G series, rated for 3-phase motor control applications. It features a 24V DC operating coil and a main contact rating of AC1 Ith=25A, making it suited for controlling AC induction motors and other resistive or inductive loads across a wide voltage range from 200V through 600V. The unit is a standard DIN rail or panel-mount device with three main poles and an integrated 1 NO auxiliary contact.

Applications
The Fuji Electric SC series contactors are widely used in industrial motor control centers (MCCs), machine tool panels, HVAC equipment, conveyor systems, pump controls, and general-purpose 3-phase motor starters. The SC-4-0/G frame is an IEC-rated design suited for panel builders and OEM machine manufacturers who need a compact, DIN rail-mountable contactor in the 18–25A range. The 24V DC coil makes it compatible with PLC-controlled systems where a low-voltage DC control circuit drives the power contactor. Fuji Electric's SC series has been a standard choice for Japanese-manufactured and internationally built industrial control equipment for several decades, and replacement and spare units remain in demand for machine maintenance and MCC rebuilds.
This Fuji Electric SC18AG SC-4-0/G non-reversing AC contactor was pulled from a working environment where it had been in service. It has not been powered up or tested at our facility. The unit appears to be in good used condition overall — the housing is intact with no cracking, all three main power terminals (L1/L2/L3 and T1/T2/T3) and the A1/A2 coil terminals are present and look clean, and the auxiliary contact block on the right side is intact. The orange coil voltage label and rating plate are legible. Some light surface soiling typical of industrial use is visible. Please review our photos and contact us with any questions.
