Product Positioning

The 3RT2015-1AF02 coil voltage is 110V AC (50/60Hz), a common voltage level on the secondary side of control transformers in Taiwanese factories' distribution boxes. Existing 110V control circuit wiring can be directly used during selection. This model has one set of normally closed (NC) auxiliary contacts, suitable for forming interlocking protection or abnormal monitoring circuits. The main circuit specifications are consistent with the same series: AC-3, rated current 7A, power 3kW at 400V; AC-1 up to 18A. The S00 minimum size with screw terminal wiring facilitates installation in control boxes with limited space.

Core Product Advantages and Features
110V AC coil, close to the voltage commonly used in Taiwanese distribution boxes.
110V is a common specification for the secondary side of most control transformers, and existing control circuit wiring can be directly used when selecting a transformer.
Built-in 1 set of normally closed (NC) auxiliary contacts
Suitable for connecting in series with interlocking protection or abnormal monitoring circuits to enhance the protection against system malfunctions.
A 7A/3kW main circuit is sufficient to meet the requirements of small three-phase motors.
The AC-3 has a rated current of 7A and a power of 3kW at 400V, while the AC-1 can reach 18A, which is sufficient to drive a typical small motor.
S00 minimum form factor, screw terminal wiring
With a size of only 57.5×45×73mm, both the main and auxiliary coil circuits use screw terminals, making installation and maintenance convenient.
