Function & Features

The Siemens 3RT2317-2AP60 contactor is specifically designed for:

• Four-pole switching of weak or non-inductive loads (AC-1): Ideal for heating elements, lighting systems, and distribution circuits where frequent switching of resistive loads is required.
• Disconnecting loads or power generation plants from the grid: Ensures safe isolation of electrical circuits.
• Transfer switching: Facilitates seamless transitions between power sources.

Key Features

• Rated Operational Current (AC-1): 22 A at 400 V / 40 °C.
• Poles: 4-pole configuration for multi-phase applications.
• Control Supply Voltage: 220 V AC (50 Hz) / 240 V AC (60 Hz) coil for reliable activation.
• Terminals: Convenient and secure spring-loaded terminals for main, auxiliary, and control circuits.
• Size: Compact S00 construction.
• Integrated Auxiliary Contacts: The basic unit includes one integrated auxiliary contact (1 NO) for enhanced control.
• Standards Compliance: Adheres to international standards including IEC 60947-1, IEC 60947-4-1, and IEC 60947-5-1 (for auxiliary switches).
• Electromagnetic Compatibility: Fulfills requirements for environment category A.
• Surge Protection (Optional): Can be retrofitted with RC elements, varistors, or diodes for damping opening surges in the coil (accessories sold separately).
• Motor Protection Integration: Compatible with SIRIUS 3RU2 thermal overload relays or 3RB3 electronic overload relays for robust motor protection (for specific motor-driven load applications, refer to 3RT23 special versions).
• Contact Reliability: Auxiliary contacts are designed for high contact reliability, suitable for switching low voltages (≤ 110 V) and currents (≤ 100 mA), and especially for solid-state circuits (≥ 1 mA at ≥ 17 V).

Protection & Safety

The Siemens 3RT2317-2AP60 contactor requires appropriate protection measures to ensure safe and reliable operation of the overall system.

• Short-circuit and Overload Protection of Main Connections: Consult the technical product data sheet for specific protection requirements for a free-standing contactor. For device combinations with overload relays or circuit breakers as motor feeders, refer to the Digital and Standard Configuration Manuals for Load Feeders.
• Short-circuit and Overload Protection of Auxiliary Connections: Information on auxiliary contact protection can be found in the technical product data sheet.
• Short-circuit and Overload Protection of Control Supply Voltage: Adherence to relevant standards for control panel configuration is crucial. Consider using suitable power supplies with current-limiting functions and proper cable dimensioning. For further recommendations, including the use of miniature circuit breakers, refer to the “Control panel tip – Selecting and dimensioning suitable power supplies quickly and reliably.”
• Overvoltage Protection: The 3RT23 contactors can be retrofitted with external surge suppressors (RC elements, varistors, diodes) for coil damping, available as separate accessories. Note that damping increases break times and opening/closing delay times of contacts.

Connection Methods

• Main Circuit: Features spring-loaded terminals for convenient and secure main circuit connections.
• Auxiliary and Control Circuit: Equipped with screw terminals for reliable auxiliary and control circuit wiring.

Expandability & Maintenance

• Auxiliary Contact Expansion: The basic unit (with its integrated auxiliary contact) can be expanded with additional auxiliary switches. Always observe the permissible configuration limits.
• Solenoid Coil Replacement: The solenoid coil of the 3RT2317-2AP60 contactor is replaceable, extending its service life.
• Accessories & Spare Parts: A comprehensive range of accessories and spare parts are available for SIRIUS 3RT2 contactors, including additional auxiliary switches, surge suppressors, and more. For detailed information, refer to the “Accessories and spare parts for SIRIUS 3RT2 contactors and SIRIUS 3RH2 contactor relays” section.
