Overview

The Siemens 3RT2317-2AB00 contactor is part of the SIRIUS 3RT23 series, renowned for its compact design, high contact reliability, and ease of use. It’s an excellent choice for applications requiring four-pole switching of resistive loads, disconnecting loads or power generation plants from the grid, and transfer switching.

Protection and Reliability:

• Comprehensive Protection: All connections (main, auxiliary, and control supply) must be protected against short circuits, overloads, and overvoltages using appropriate measures. Refer to the technical product data sheet and configuration manuals for detailed guidance on device combinations and protection device selection.
• Overvoltage Protection: The 3RT23 contactors can be retrofitted with surge suppressors (RC elements, varistors, diodes) for effective damping of opening surges in the coil, protecting sensitive control components.
• Electromagnetic Compatibility (EMC): Fulfills the requirements for environment category A. For use with frequency converters, specific configuration notes in the Equipment Manual must be observed.
• Auxiliary Contact Reliability: Auxiliary contacts are designed for high contact reliability, particularly suitable for switching low voltages (≤ 110 V) and currents (≤ 100 mA), and ideal for solid-state circuits.

Connection Methods:

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

Motor Protection Integration:

For robust motor protection against overload, the 3RT2317-2AB00 can be seamlessly combined with Siemens 3RU2 thermal overload relays or 3RB3 electronic overload relays.

Operating Mechanism:

This version features a conventional AC operating mechanism, controlled via the control supply voltage connections A1-A2.

Maintenance and Expansion:

• Replaceable Solenoid Coil: The solenoid coil can be easily replaced for maintenance or repair.
• Auxiliary Switch Expansion: The basic unit can be expanded with additional auxiliary switches, offering increased flexibility for complex control tasks. The permissible configuration must be observed.

Accessories and Spare Parts:

A wide range of accessories and spare parts are available for the SIRIUS 3RT2 contactors and 3RH2 contactor relays. Please refer to the dedicated accessory and spare part overviews for detailed ordering information.
