Siemens 3RT2015-1AP02 AC contactor, 230V AC, 1NC auxiliary contact

Product Positioning

The 3RT2015-1AP02 is the smallest S00-shaped contactor in the Siemens SIRIUS 3RT2 series. It has a coil voltage of 230V AC (50/60Hz) and a built-in normally closed (NC) auxiliary contact, allowing direct connection in series with interlocking protection or fault monitoring circuits without the need for additional contact modules. The main circuit has a rated current of 7A and power of 3kW under AC-3 and 400V conditions, and up to 18A under AC-1 conditions. It is suitable for direct starting control of small three-phase motors and features screw terminal wiring, making installation and maintenance relatively simple.

Core Product Advantages and Features

S00's smallest form factor saves space in distribution boxes.

With a body size of only 57.5×45×73mm, it is the smallest in the SIRIUS 3RT2 series, making it suitable for space-constrained control panels and machine-side electrical distribution boxes.

230V AC coil with 1NC auxiliary contacts

The built-in normally closed auxiliary contact can be directly used for interlock protection or abnormal signal circuits, eliminating the need for an external auxiliary contact socket.

7A/3kW main circuit, reliable switching for small motors

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

Mechanical life of 30 million cycles, easy maintenance with screw terminals.

The main circuit, auxiliary circuit, and coil terminals are all screw-type, making wiring and installation convenient and ensuring high stability over long-term use.
