Siemens 3RT2017-1CK64-3MA0 Power Contactor, 12A, 5.5kW, 110/120V AC, 2 NO + 2 NC, Size S00 Original Brand New

Overview

The Siemens 3RT2017-1CK64-3MA0 is a high-performance power contactor designed for reliable and efficient switching of electrical loads. This 3-pole contactor is rated for AC-3e/AC-3 applications, handling up to 12 A and 5.5 kW at 400 V. It operates with a control voltage of 110 V AC (50 Hz) or 120 V AC (60 Hz) and features a pre-installed varistor for surge protection. The compact S00 size makes it ideal for space-constrained industrial applications.

Key Features & Benefit

• Robust Performance: Handles demanding AC-3e/AC-3 applications with a 12 A and 5.5 kW rating.
• Integrated Surge Protection: The pre-wired varistor protects the contactor and connected equipment from voltage spikes, extending its lifespan.
• Versatile Auxiliary Contacts: Equipped with 2 normally open (NO) and 2 normally closed (NC) auxiliary contacts, providing flexibility for control and signaling circuits.
• Secure and Reliable Connections: Screw terminals ensure a strong and stable connection, reducing the risk of failure.
• Compact Design: The size S00 form factor allows for easy integration into control panels and machinery with limited space.
• Captive Auxiliary Switch: The captive auxiliary switch design simplifies installation and prevents parts from being misplaced.

Function

• Motor Control: Ideal for starting, stopping, and reversing three-phase asynchronous motors.
• Load Switching: Suitable for switching various resistive, inductive, and capacitive loads in industrial and commercial settings.
• Control System Integration: The auxiliary contacts can be used for feedback, interlocking, and other control functions.
