Function

The Siemens 3RT2316-1AP00 contactor primarily functions as an electrically operated switch, designed to make or break connections in a power circuit. Its core functions include:

• Switching Non-Inductive Loads (AC-1): Efficiently controls circuits with resistive or slightly inductive loads, such as heating elements, lighting, or distribution circuits.
• Disconnecting Loads: Provides a reliable means to isolate electrical loads from the main power supply for maintenance or safety purposes.
• Integrating Power Generation Plants: Can be used in systems to connect or disconnect distributed power sources (e.g., solar inverters, generators) from the grid.
• Transfer Switching: Facilitates the switching between different power sources in applications requiring redundancy or alternative supply.

Standards

• IEC 60947-1
• IEC 60947-4-1
• IEC 60947-5-1 (for auxiliary switches)

Protection of Device Connections

All connections to the Siemens 3RT2316-1AP00 contactor must be adequately protected against overload and short circuits.

• Main Circuit Protection: For detailed information on protecting a standalone contactor, refer to the technical product data sheet. For combinations with overload relays or circuit breakers in motor feeder applications, consult the Digital Configuration Manual for load feeders or the Configuration Manual for load feeders.
• Auxiliary Circuit Protection: Specific guidelines for protecting auxiliary contacts are available in the technical product data sheet.
• Control Supply Voltage Protection: Adherence to relevant standards and regulations for control panel configuration is essential. Suitable power supplies with current-limiting functions are recommended, considering the contactor’s load characteristics (inrush current, switch-on, and holding power). Miniature or circuit breakers may also be used in control circuits.

Overvoltage Protection at Control Supply Voltage

The 3RT23 contactors (like the 3RT2316-1AP00), when supplied without a coil circuit, can be retrofitted with surge suppressors such as RC elements, varistors, diodes, or diode assemblies. These accessories, available separately, help dampen opening surges in the coil. Please note that damping may increase the break times of the contactor and the opening/closing delay times of NO/NC contacts. Refer to the Equipment Manual for detailed information on how damping influences time response.

Connection Methods

• Main Circuit: This 3RT231 contactor features robust screw terminals for secure main circuit connections.
• Auxiliary and Control Circuit: Auxiliary and control circuits are also connected via reliable screw terminals.

Electromagnetic Compatibility (EMC)

The Siemens 3RT2316-1AP00 contactor fulfills the requirements for environment category A, ensuring reliable performance in industrial environments. When used with frequency converters, specific configuration notes in the Equipment Manual must be observed.

Contact Reliability of Auxiliary Contacts

For switching low voltages (≤ 110 V) and currents (≤ 100 mA), the integrated auxiliary contact (1 NO) of this 3RT23 contactor ensures high contact reliability. These contacts are particularly suitable for solid-state circuits with currents ≥ 1 mA at voltages of 17 V and higher.

Motor Protection Compatibility

While the 3RT2316-1AP00 is an AC-1 contactor, for applications requiring motor protection against overload, it can be combined with Siemens 3RU2 thermal overload relays or 3RB3 electronic overload relays.

Operating Mechanism Type

The 3RT2316-1AP00 features a conventional AC operating mechanism, controlled via the A1-A2 control supply voltage connections. Specific operating ranges are detailed in the technical product data sheet.

Auxiliary Contact Configuration

The 3RT2316-1AP00 (a 3RT231 contactor) comes with one integrated auxiliary contact (1 NO) in its basic unit. The basic unit can be further expanded with additional auxiliary switches, provided the permissible configuration is observed. For detailed information on fitting auxiliary switches, refer to the “Auxiliary switches, instantaneous” overview.

Accessories and Spare Parts

A range of accessories and spare parts are available for the Siemens SIRIUS 3RT2316-1AP00 contactor, including surge suppressors, additional auxiliary switches, and replacement solenoid coils. For a comprehensive list, please refer to the “Accessories and spare parts for SIRIUS 3RT2 contactors and SIRIUS 3RH2 contactor relays” documentation.

Application

The Siemens 3RT2316-1AP00 contactor is an excellent choice for a variety of industrial and commercial applications, including:

• Four-pole switching of weak or non-inductive loads (AC-1)
