Product Positioning

The 3RT2027-1BB40 is a Siemens SIRIUS 3RT20 series S0-size three-pole power contactor. Its control coil is powered by a 24V DC power supply, with a rated operating current (AC-3) of 32A, and can handle 400V switching loads up to 15kW motors. The main body has one set of normally open and one set of normally closed auxiliary contacts, allowing direct wiring feedback of the main contact's operating state without the need for additional auxiliary contact blocks. The main circuit terminals can be fitted with 1 to 10 square millimeter wires, while the auxiliary circuit terminals can be fitted with 0.5 to 2.5 square millimeter wires. It has an IP20 front protection rating, a rated insulation voltage of 690V for both main and auxiliary circuits, and a mechanical life of 10 million operations. It is a common standard main contactor in 24V DC control systems.

Core Product Advantages and Features
24V DC coil design
This system uses a DC power supply to drive the electromagnetic system, making it suitable for direct drive applications of electromechanical panels and PLC outputs in DC 24V control circuits.
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, which can be directly wired to monitor the action status of the main contacts.
690V insulation/IP20 protection
The main and auxiliary circuits have a rated insulation voltage of 690V, a front protection rating of IP20, and a mechanical life of 10 million operations.
