Product Positioning

The 3RT2015-1AN22 uses a 220V AC (50/60Hz) coil, which is one of the common voltage levels on the secondary side of many control transformers. It has a built-in set of normally closed (NC) auxiliary contacts, suitable for forming interlocking protection or abnormal monitoring circuits, without the need for additional auxiliary contact modules. The main circuit maintains the same AC-3, 400V 7A/3kW specifications as the SIRIUS 3RT2015 series, and AC-1 can reach 18A. The S00 minimum size and screw terminal design make it easy to replace or add configurations in existing distribution boxes.

Core Product Advantages and Features

220V AC coil, corresponding to common control voltages

It conforms to the 220V specification of the secondary side of most control transformers, making it convenient to directly reuse existing distribution box lines.

Built-in 1 set of normally closed (NC) auxiliary contacts

It can be directly connected to interlocking protection or safety monitoring circuits to improve the system's ability to prevent malfunctions.

7A/3kW main circuit, supporting small three-phase motors

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

S00 minimum form factor, screw terminal wiring

Measuring only 57.5×45×73mm and featuring a screw terminal design, it is suitable for control panel configurations with limited space.
