Siemens 3RT2017-1AK61 Power Contactor SIRIUS S00, 12A, 110/120V AC Coil Original Brand New

Overview: Siemens 3RT2017-1AK61 SIRIUS 3RT2 Power Contactor

The Siemens 3RT2017-1AK61 is a high-performance, compact 3-pole power contactor from the globally recognized SIRIUS 3RT2 series. Engineered for switching motors and general resistive loads (AC-3e/AC-3), this component is a robust solution for demanding industrial control applications. Featuring a small Size S00 frame, it delivers a powerful switching capacity of 12 A resistive current and 5.5 kW at 400 V.

The integrated AC coil operates on 110 V AC (50 Hz) or 120 V AC (60 Hz), making it highly versatile for various power systems. Installation and wiring are made secure and straightforward with its reliable screw terminals. This model also includes one integrated Normally Open (1 NO) auxiliary contact for use in control circuits.

Benefits and Advantages

• Compact Design (Size S00): Space-saving and ideal for integration into tight control panels and motor starters.
• High Performance: Reliable switching of motors up to 5.5 kW at 400V.
• Global Standard: Complies with major international standards (IEC, UL, CSA, CCC), making it suitable for worldwide use.
• Integrated Auxiliary Contact: Comes standard with $1\text{ NO}$ auxiliary contact, simplifying control circuit wiring.
• Robust & Durable: Exceptional mechanical service life (30 million cycles) ensures long-term reliability and reduced maintenance.
• Easy Installation: Features secure screw terminals and can be mounted on a DIN rail, snap-on, or by threading.
• SIRIUS System Compatibility: Seamlessly integrates with other Siemens SIRIUS devices like overload relays (e.g., 3RU2) and other accessories for a complete motor starter solution.

Function and Application

The 3RT2017-1AK61 power contactor is primarily used in industrial automation and control for:

1. Switching 3-Phase Motors: Starting and stopping three-phase AC motors (AC-3/AC-3e duty).
2. Controlling Resistive Loads: Switching heating elements, lighting, and other non-motor loads.
3. Use in Motor Starter Combinations: Typically paired with a thermal or electronic overload relay to form a complete, protected motor starter.
4. Integration into Control Systems: The integrated auxiliary contact provides feedback or enables interlocking in complex machine control logic.

Technical Features

• Protection: Finger-safe according to EN 50274.
• Insulation: High impulse voltage resistance (6 kV) and insulation voltage (690 V).
• Low Power Loss: Contributes to energy efficiency within the control cabinet.
• Climatic Resistance: Suitable for use worldwide in various environmental conditions (operating temperature: −25∘C to +60∘C).
