Function

• Four-Pole Switching: Capable of switching four independent circuits or phases simultaneously.
• Load Disconnection: Effectively disconnects weak or non-inductive loads from the grid.
• Power Generation Plant Integration: Suitable for transfer switching and managing power flow in generation systems.
• Control Circuit Integration: Functions as a key component in industrial control panels for automated processes.

Standards & Protection:

The Siemens 3RT2317-2AK60 contactor adheres to rigorous international standards:

• IEC 60947-1: General rules for low-voltage switchgear and control gear.
• IEC 60947-4-1: Contactors and motor-starters.
• IEC 60947-5-1: Control circuit devices and switching elements (for auxiliary switches).

Protection Measures:

• Short-Circuit and Overload Protection: All connections (main, auxiliary, control supply) must be protected using appropriate measures, such as fuses or circuit breakers. Refer to the technical product data sheet and configuration manuals for detailed guidance.
• Overvoltage Protection (Coil): The 3RT23 contactors can be retrofitted with external surge suppressors (RC elements, varistors, diodes) to dampen opening surges in the coil, protecting sensitive control circuitry.

Connection Methods:

• Main Circuit: Features convenient spring-loaded terminals, providing secure and tool-free wiring.
• Auxiliary and Control Circuit: Utilizes screw terminals for reliable connections.

Electromagnetic Compatibility (EMC):

The contactor fulfills the requirements for environment category A, ensuring stable operation in typical industrial settings. When used with frequency converters, refer to the Equipment Manual for specific configuration notes.

Contact Reliability of Auxiliary Contacts:

The integrated auxiliary contacts are designed for high reliability, particularly for switching low voltages (≤ 110 V) and currents (≤ 100 mA), making them ideal for solid-state circuits (≥ 1 mA at ≥ 17 V).

Motor Protection Compatibility:

While designed for AC-1 loads, the 3RT23 contactor can be combined with Siemens 3RU2 thermal overload relays or 3RB3 electronic overload relays for comprehensive protection of connected motors (when used in AC-3 applications).

Operating Mechanism:

• Conventional AC Operating Mechanism: This version features a reliable AC operating mechanism, controlled via the A1-A2 control supply voltage connection.

Maintenance & Expandability:

• Replaceable Solenoid Coil: The solenoid coil can be easily replaced, extending the lifespan of the contactor.
• Auxiliary Contact Expansion: The basic unit of the 3RT231 contactor includes one integrated auxiliary contact. This can be expanded with additional auxiliary switches for increased signaling and control capabilities.

Accessories and Spare Parts:

A wide range of accessories and spare parts are available for SIRIUS 3RT2 contactors and 3RH2 contactor relays, including:

• Surge suppressors
• Auxiliary switches (instantaneous)
• Replacement solenoid coils
