3. Flexible Integration: The 3RT2 series is perfectly matched to other SIRIUS modular components (such as overload relays and circuit breakers), simplifying the design and assembly of load feeders.
4. Integrated Auxiliary Contacts: Comes standard with $1\text{ NO}+1\text{ NC}$ auxiliary contacts, reducing the need for external add-on blocks in many applications.
5. Secure Wiring: Features robust screw terminals for a reliable, high-contact force connection in demanding environments.
6. Worldwide Approval: Climate-proof design with international approvals (IEC, UL/CSA, CCC, etc.) for global use.

Function

The 3RT2027-1AG60 Power Contactor functions as an electrically operated switch for controlling an electric power circuit. It is primarily used for switching 3-phase AC motors, heating elements, lighting systems, and power factor correction equipment. The $100\text{ V AC}$ control voltage energizes the coil, which closes the main contacts to supply power to the load, such as a $15\text{ kW}$ motor. The built-in auxiliary contacts provide status feedback to control systems (PLCs) or enable interlocking functions.

Application

This contactor is ideal for use in:

• Industrial Motor Control Centers (MCCs)
• Pump and Fan Control
• Conveyor Systems
• Manufacturing and Process Automation
• Control of heating and lighting loads
