Siemens 3RT2018-1AK62 SIRIUS Power Contactor, 16A, 7.5kW, 110/120V AC Coil Original Brand New

Overview

The Siemens 3RT2018-1AK62 is a high-performance, compact SIRIUS 3RT2 power contactor designed for switching motors and general resistive loads up to $7.5\text{ kW}/400\text{ V}$ (AC-3e/AC-3). This 3-pole contactor features a 110 V AC (50 Hz) / 120 V AC (60 Hz) operating coil and an integrated 1 NC (Normally Closed) auxiliary contact for signaling or interlock circuits. Its compact Size S00 design and robust screw terminals make it an ideal choice for reliable, space-saving installation in industrial control panels, ensuring maximum contact reliability and ease of use.

Benefit

• Exceptional Reliability: Part of the proven Siemens SIRIUS modular system, ensuring high operational reliability and a long mechanical service life (up to $30$ million switching cycles).
• Space-Saving Design: The compact Size S00 form factor allows for efficient panel design and installation in tight spaces.
• Global Standard Compliance: Approved for worldwide use (IEC, UL/CSA, CCC), making it suitable for export-oriented machinery and systems.
• Ease of Wiring: Features widely preferred screw terminals for secure, robust, and familiar main and control circuit connections.
• Integrated Auxiliary Contact: The built-in $1\text{ NC}$ contact simplifies wiring for control and signaling functions, reducing the need for separate auxiliary blocks.
• Future-Proof: IE3/IE4 ready for high-efficiency motor applications, aligning with current energy-saving standards.

Function & Application

The 3RT2018-1AK62 power contactor is the central switching element in various industrial applications.

• Motor Switching: Primarily used for the reliable Direct-On-Line (DOL) switching of standard 3-phase AC motors up to $7.5\text{ kW}/10\text{ HP}$.
• Resistive Loads: Suitable for switching non-motor loads such as heating elements, lighting systems, and capacitors (AC-1 operation up to $22\text{ A}$).
• Integration: Seamlessly integrates with SIRIUS 3RV2 motor starter protectors and 3RU2 thermal overload relays to form a complete, coordinated load feeder/motor starter assembly.
• Control Systems: Used in conjunction with PLCs, pushbuttons, or other control devices to safely start, stop, and control electrical loads.
