Product Positioning

The 3RT2027-1AR60 is a Siemens SIRIUS 3RT20 series S0-size three-pole power contactor. The control coil is rated at 400V/50Hz, but can be used with 400 to 440V power supplies at 60Hz. The rated operating current (AC-3) is 32A, and it can switch 15kW motor loads at 400V. The main body has one set of normally open and one set of normally closed auxiliary contacts. The main circuit uses screw terminals. It weighs approximately 0.417 kg and belongs to the AC-3e/AC-3 switching class of high-voltage control coil. It is suitable for motor control panels in factories where the power distribution voltage has reached 400V and the control circuit is directly driven by the power voltage, eliminating the need for an additional control transformer.

Core Product Advantages and Features
400V AC coil, no control transformer required
The coil's rated voltage is compatible with common 400V power voltages, allowing it to be directly driven by the power source, simplifying wiring.
Dual-frequency compatibility (50Hz/60Hz)
The coil supports 50Hz 400V and 60Hz 400~440V, suitable for export or applications requiring dual-frequency power supplies.
32A/15kW main circuit capacity
The AC-3 has a rated operating current of 32A and can handle a 15kW motor load at 400V, corresponding to S0 chassis dimensions.
Built-in 1NO+1NC auxiliary contacts
The main body is equipped with one set of normally open and one set of normally closed instantaneous action auxiliary contacts for easy feedback wiring.
