Siemens 3RT2027-1AP00 Contactor, SIRIUS 3RT2, 32A, 15kW, 230V AC, S0 Original Brand New

Overview: Siemens 3RT2027-1AP00 SIRIUS 3RT2 Power Contactor

The Siemens 3RT2027-1AP00 is a high-performance, 3-pole Power Contactor from the renowned SIRIUS 3RT2 series. Designed for switching electric motors and other industrial loads, this compact Size S0 contactor offers exceptional reliability and efficiency.

Key specifications include:

• Rated Operational Current (Ie​) (AC-3e/AC-3): 32 A
• Rated Operational Power (Pe​): 15 kW at 400 V
• Coil Voltage (Us​): 230 V AC, 50 Hz
• Auxiliary Contacts: Integrated 1 NO (Normally Open) + 1 NC (Normally Closed)
• Connection Type: Screw Terminal
• Contactor Size: S0

As part of the modular SIRIUS system, the 3RT2027-1AP00 is easily combinable with overload relays (e.g., SIRIUS 3RU2/3RB3) and other control components to build a complete, factory-tested load feeder.

Key Features and Benefit

• High Performance in a Compact Design: The Size S0 unit efficiently controls up to 15 kW motors, saving crucial panel space.
• Motor Control Reliability: Rated for AC-3 and the energy-efficient AC-3e operation, ensuring safe and reliable switching of motor loads.
• Integrated Auxiliary Contacts: Features a built-in 1 NO and 1 NC auxiliary switch, simplifying wiring and reducing the need for external contact blocks.
• Universal Compatibility: As an IEC-rated device, it is approved for worldwide use (IEC, UL/CSA), making it suitable for global machinery export.
• Simple Wiring: Equipped with robust screw terminals for secure and straightforward main and control circuit connection.
• System Integration: Fully compatible with the modular SIRIUS system accessories, including surge suppressors, connection modules, and function modules, to reduce wiring complexity.
• IE3/IE4 Ready: Optimized for use with modern, energy-efficient IE3 and IE4 motors.

Function

The Siemens 3RT2027-1AP00 functions as an electromechanical switching device used to remotely control the flow of electrical power to a load, typically a 3-phase electric motor. When the 230 V AC control coil is energized, the three main NO contacts close, connecting the motor to the 400 V power supply. The integrated auxiliary contacts provide a signal (1 NO and 1 NC status) for interlocking, signaling, and control circuits.
