Product Positioning

Both the 3RT2015-1AF01 and 1AF02 use a 110V AC (50/60Hz) coil, conforming to the common secondary voltage of control transformers manufactured in Taiwan. The difference lies in the auxiliary contact type: one set of normally open (NO) contacts, suitable for feedback of contactor operation status, driving panel indicator lights, or serving as digital input signal points for control systems. The main circuit specifications remain unchanged: AC-3, 400V 7A/3kW, AC-1 up to 18A. The S00 is compact in size and uses screw terminal wiring, facilitating quick installation and subsequent maintenance.

Core Product Advantages and Features

1 set of normally open (NO) auxiliary contacts feedback action status

It facilitates the extraction of ON/OFF signals to drive indicator lights or for monitoring in the control system.

110V AC coil, sharing the same voltage rating as 1AF02.

To facilitate the selection of different auxiliary contact types for interlocking or signal requirements within the same control box.

7A/3kW main circuit capacity

The AC-3 has a rated current of 7A and a power output of 3kW at 400V, while the AC-1 can reach 18A. It is suitable for direct starting of small three-phase motors.

S00 minimum size, screw terminal design

With a size of only 57.5×45×73mm, both the main and auxiliary coil circuits use screw terminals, making installation and maintenance convenient.
