Siemens 3RT2015-1AK61 AC contactor, 110/120V AC dual frequency, 1NO auxiliary contact.

Product Positioning

The 3RT2015-1AK61 features a unique coil design, indicating both 110V AC (50Hz) and 120V AC (60Hz) ratings. A single coil can handle both 50Hz and 60Hz mains frequencies, making it convenient for manufacturers whose machines need to be exported to both the European 50Hz market and the American/Taiwan 60Hz market, reducing the number of models they need to stock. The auxiliary contacts are one set of normally open (NO) contacts, suitable for feedback of operating status or drive indication. The main circuit AC-3 provides 7A/3kW at 400V, and AC-1 provides up to 18A. It belongs to the SIRIUS 3RT2015 S00 smallest form factor series, and screw terminal wiring allows for quick installation.

Core Product Advantages and Features

110V/50Hz, 120V/60Hz dual-frequency coil

A single part number can cover the requirements of 50Hz and 60Hz power grids, effectively simplifying the preparation and selection of materials for export machines.

1 set of normally open (NO) auxiliary contacts

It facilitates feedback of contactor operating status, drive indicator lights, or serves as a monitoring signal point for the control system.

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. Both are suitable for general small three-phase motor control.

S00 compact design with screw terminals

With a size of only 57.5×45×73mm, it is easy to install in control panels with limited space, and maintenance is also more time-saving.
