Product Positioning

The 3RT2023-1AK60 is a coil version of the Siemens SIRIUS 3RT2023 series specifically designed for 110/120V mains. It operates at 110V at 50Hz and 120V at 60Hz, with a pull-in power of approximately 68/67VA and a holding power of approximately 7.9/6.5VA. It is commonly found in control circuits for North American specifications or some export equipment, and can directly utilize locally used low-voltage control power supplies. The main circuit maintains the series standard, with an AC-3 rated current of 9A and a rated power of 4kW/400V. Auxiliary contacts are standardly equipped with 1NO+1NC instantaneous contacts, and both main and auxiliary circuits use screw terminals. The product can withstand an operating temperature range of -25°C to 60°C, and features IP20 protection and a 10 million mechanical lifespan, making it suitable for harsh installation environments such as those with large temperature differences or outdoor computer rooms.

Core Product Advantages and Features

AC110/120V Dual-Rate Coil

50Hz corresponds to 110V, and 60Hz corresponds to 120V, which is suitable for North American specifications or some export equipment that can directly use the local control power supply.

Wide temperature range design

It can operate stably in the range of -25°C to 60°C, making it suitable for outdoor distribution boxes or computer room environments with large temperature differences.

AC-3 9A/4kW main circuit

Maintaining the standard rating of the 3RT2023 series, with a current of 9A and a power of 4kW at 400V, it is suitable for general motor start-up and shut-down control.

1NO+1NC auxiliary contact

It comes standard with one set of normally open and one set of normally closed instantaneous contacts, along with screw terminals, for easy signal feedback and interlocking wiring.
