Product Positioning

The 3RT2024-1AG20 is the 110V control voltage version of the Siemens SIRIUS 3RT2 series S0 frame AC contactor. The coil can operate on a 50Hz or 60Hz power supply. The main circuit AC-3 rated current is 12A, rated power is 5.5kW (400V), and it is a 3-pole design. It has one set of NO+1 set of NC instantaneous auxiliary contacts built into the body, providing basic operational feedback and interlocking functions. It is suitable as a main component in the direct starting circuit of small three-phase motors in a 110V control power supply system.

Core Product Advantages and Features
110V Dual-Frequency Coil
The coil voltage is 110V AC, and it can be normally held at both 50Hz and 60Hz. It is suitable for the secondary output of various control transformers.
Standard 1NO+1NC auxiliary contact
The device has one set of normally open and one set of normally closed auxiliary contacts built in, covering most interlocking and indicating applications, so there is no need to purchase contact sockets separately.
S0 chassis with compact size
With a structural dimension of 45×85×97mm, the distribution box features high installation density, facilitating panel space planning.
High frequency switching durability
With a mechanical life of approximately 10 million cycles, it is suitable for control loops of production line equipment that require frequent start-stop operations.
