For reliable switching of power to your electric circuit, choose this contactor from ABB. When current passes through its internal electromagnetic coil, it causes the contacts to close, sending electrical energy to attached circuits. The unit has three poles and an auxiliary contact, making it suitable for your 3-phase electric motors. It has a broad operating temperature range between -40°C and +55°C, so performs reliably in challenging environments. With a maximum switching frequency of 3600 cycles per hour, you can count on this component for constant use.

• Contact current rating of 27A can handle the demands of high-power systems
• Shock-resistant for use in heavy-duty applications
• DIN rail mounting makes it quick to install
• Contact opening between 4 and 11ms and contact closing between 10 and 26ms for rapid switching

• Industrial pumps and fans
• Medical technology
• Lighting systems

This auxiliary contact monitors the contact state of the main contactor and sends a signal to the control unit if the contacts change position.

This contactor has a mechanical durability rating of 10 million cycles, making it suitable for long-term use.
