Featuring a 24V AC 50/60 Hz control voltage and convenient screw terminals, this compact Size S00 contactor is an essential component for various industrial applications, including disconnecting loads, power generation plant integration, and transfer switching. Built to IEC standards, the 3RT2317-1AB00 offers exceptional performance and easy integration into control panels and systems.

Key Features & Benefit

• Reliable AC-1 Switching: Specifically engineered for switching 4-pole non-inductive or weakly inductive loads, ensuring stable and efficient operation.
• High Current Rating: Handles up to 22A at 400V/40°C, suitable for a wide range of general-purpose applications.
• Versatile Control Voltage: Operates on a standard 24V AC, 50/60 Hz control supply, simplifying integration into existing control circuits.
• Secure Screw Terminals: Provides robust and straightforward wiring connections for main and auxiliary circuits.
• Compact Size S00: Optimizes space within control cabinets, making it ideal for applications with limited enclosure room.
• Standards Compliant: Meets stringent international standards including IEC 60947-1, IEC 60947-4-1, and IEC 60947-5-1 (for auxiliary switches), ensuring safety and compatibility.
• Integrated Auxiliary Contact: The 3RT231 contactors come with an integrated auxiliary contact, enhancing control versatility.
• Expandable Functionality: Easily expandable with additional auxiliary switches (sold separately) to meet specific application requirements.
• Overvoltage Protection Ready: Can be retrofitted with surge suppressors (RC elements, varistors, diodes) for enhanced coil protection (accessories sold separately).
• Motor Protection Compatibility: Seamlessly integrates with SIRIUS 3RU2 thermal overload relays or 3RB3 electronic overload relays for comprehensive motor protection.

Function & Protection

• Short-Circuit & Overload Protection:
  • Main Connections: Requires suitable external short-circuit and overload protection. Refer to the technical product data sheet and configuration manuals for detailed guidance on free-standing contactors and device combinations (contactor with overload relay or circuit breaker as motor feeder).
  • Auxiliary Connections: Information on protection is available in the technical product data sheet.
  • Control Supply Voltage Connections: Protection must adhere to relevant standards for control panel configuration. Consider power supplies with current-limiting functions and suitable protection devices, accounting for contactor load characteristics (inrush current, switch-on power, holding power). Recommendations for miniature or circuit breakers in control circuits are available in Siemens’ “Control panel tip – Selecting and dimensioning suitable power supplies quickly and reliably.”
• Overvoltage Protection at Control Supply: 3RT23 contactors (without pre-installed coil damping) can be equipped with external RC elements, varistors, diodes, or diode assemblies for damping opening surges. Note that damping increases break and delay times.
• Electromagnetic Compatibility (EMC): Fulfills requirements for environment category A. For use with frequency converters, refer to the Equipment Manual for configuration notes.
• Contact Reliability of Auxiliary Contacts: Auxiliary contacts of 3RT contactors are designed for high contact reliability, especially suitable for low voltages (≤ 110V) and currents (≤ 100mA), and for solid-state circuits with currents ≥ 1mA at 17V and higher.
• Motor Protection Integration: The 3RT2317-1AB00 is compatible with Siemens SIRIUS 3RU2 thermal overload relays and 3RB3 electronic overload relays for comprehensive motor overload protection.

Connection Methods:

• Main Circuit: Features robust screw terminals.
• Auxiliary & Control Circuit: Utilizes reliable screw terminals for secure connections.

Operating Mechanism:

• The 3RT2317-1AB00 features a conventional AC operating mechanism, controlled via the A1-A2 control supply voltage connections. Refer to the technical product data sheet for specific operating ranges.

Maintenance & Expansion:

• Solenoid Coil Replacement: The solenoid coil of the 3RT2317-1AB00 can be replaced.
• Auxiliary Contact Fitting: This basic unit includes an integrated auxiliary contact. Further expansion with additional auxiliary switches is possible, observing permissible configurations. Refer to “Auxiliary switches, instantaneous → Overview” for detailed information.
• Accessories & Spare Parts: A wide range of accessories and spare parts are available for SIRIUS 3RT2 contactors to extend functionality and simplify maintenance.

Application

The Siemens 3RT2317-1AB00 contactor is ideal for a variety of industrial switching tasks, including:

• Four-pole switching of weak or non-inductive loads (AC-1)
• Disconnecting general loads from the electrical grid
• Integration and disconnection of power generation plants (e.g., solar, wind)
• Transfer switching applications
