Product Positioning

The 3RT2024-1AK60 is an S0-frame AC contactor from the Siemens SIRIUS 3RT2 series, designed for 110V/120V control power supplies. The coil specifications are 110V AC 50Hz or 120V AC 60Hz, allowing the same part number to accommodate two common regional power frequencies. This is particularly useful for integrators serving both Taiwanese and North American equipment specifications. The main circuit maintains the standard 3-pole, AC-3 rated 12A/5.5kW (400V) S0-frame specifications, and includes one set of NO+1 NC auxiliary contacts. Screw terminal wiring allows for direct mounting on a 35mm standard DIN rail.

Core Product Advantages and Features
110V/120V Dual-Frequency Compatibility
The coil can be held normally under 110V AC 50Hz or 120V AC 60Hz conditions, and a single part number can meet the needs of production line equipment with different power supply frequencies.
Built-in 1 NO + 1 NC auxiliary contact
Basic normally open/normally closed signals can be obtained without the need for auxiliary contact sockets, simplifying control circuit wiring.
S0 chassis standard compatible
It shares the same mechanism dimensions and mounting holes as other 3RT2024 series, which facilitates spare parts management and on-site replacement.
Industrial-grade durable design
With a mechanical life of approximately 10 million cycles, it can withstand 6kV impulse voltage and is suitable for production line equipment that operates continuously for a long time.
