Siemens SIRIUS 3RT2316-2AH00 4-Pole Contactor AC-1, 18A, 48V AC, Spring Terminal, Size S00 Original Brand New

Overview

The Siemens SIRIUS 3RT2316-2AH00 is a high-performance 4-pole contactor designed for efficient switching of resistive and non-inductive loads (AC-1) up to 18 A at 400 V / 40 °C. Featuring a reliable 48 V AC (50/60 Hz) spring-loaded terminal operating mechanism and a compact S00 size, this contactor is an ideal solution for a wide range of industrial control applications. As part of the SIRIUS 3RT2 series, it offers robust construction, easy integration, and adherence to leading international standards, ensuring dependable operation in demanding environments.

Function

• 4-Pole Switching (AC-1): Designed for switching weak or non-inductive loads, making it suitable for heating, lighting, and general power distribution applications.
• Load Disconnection: Effectively disconnects loads or power generation plants from the grid.
• Transfer Switching: Capable of facilitating transfer switching operations.
• Control Circuit Integration: Integrates seamlessly into control circuits with its 48V AC control voltage.
• Spring-Loaded Terminals: Provides fast, reliable, and vibration-resistant connections for main and control circuits.

Benefit

• High Reliability: Built to Siemens’ rigorous quality standards, ensuring long-term operational stability and reduced downtime.
• Space-Saving Design: Compact S00 size allows for efficient panel layout and optimization of cabinet space.
• Easy Installation: Spring-loaded terminals simplify wiring, reducing installation time and potential wiring errors.
• Versatile Application: Suitable for various AC-1 applications, offering flexibility in industrial and commercial setups.
• Enhanced Safety: Designed with comprehensive protection guidelines for short-circuit, overload, and overvoltage, contributing to safer electrical systems.
• Expandable Functionality: Can be easily expanded with auxiliary switches and compatible with 3RU2 thermal or 3RB3 electronic overload relays for motor protection.

Protection of Device Connections:

• Short-Circuit and Overload Protection (Main Connections): Refer to the technical product data sheet and Digital/Configuration Manuals for load feeders for detailed guidance on protection for free-standing contactors and device combinations (contactor with overload relay or circuit breaker).
• Short-Circuit and Overload Protection (Auxiliary Connections): Specific information available in the technical product data sheet for auxiliary contacts.
• Short-Circuit and Overload Protection (Control Supply Voltage): Adherence to relevant standards for control panel configuration is crucial. Consideration of suitable power supplies with current-limiting functions and appropriate protection devices (e.g., miniature circuit breakers) is recommended.
• Overvoltage Protection (Control Supply Voltage): 3RT23 contactors can be retrofitted with RC elements, varistors, diodes, or diode assemblies for damping opening surges. (Note: Damping increases break times and delays of contacts.)

Connection Methods:

• Main Circuit: Spring-loaded terminals with convenient plug-in design for device connector.
• Auxiliary and Control Circuit: Screw terminals.

Electromagnetic Compatibility (EMC): The contactors meet the requirements for environment category A. When used with frequency converters, specific configuration notes in the Equipment Manual must be observed.

Contact Reliability of Auxiliary Contacts: For switching voltages $\le$ 110 V and currents $\le$ 100 mA, the auxiliary contacts of 3RT contactors (and 3RH contactor relays) offer high contact reliability, suitable for solid-state circuits with currents $\ge$ 1 mA at voltages of 17 V and higher.

Motor Protection: While the 3RT2316-2AH00 is primarily for AC-1 loads, it can be combined with Siemens 3RU2 thermal overload relays or 3RB3 electronic overload relays for applications requiring motor protection.

Operating Mechanism: The 3RT2316-2AH00 features a conventional AC operating mechanism with a 48V AC control supply voltage (A1-A2).

Maintenance and Replacement:

• Solenoid Coil Replacement: Possible for this 3RT23 contactor.
• Contacts: Only contacts for 3RT233 contactors can be replaced (not applicable to this 3RT231 model for contacts).

Auxiliary Contacts and Expansion:

• Integrated Auxiliary Contact: The 3RT231 basic unit comes with one integrated auxiliary contact.
• Expansion Possibilities: All basic units can be expanded with additional auxiliary switches, adhering to permissible configurations. Refer to “Auxiliary switches, instantaneous → Overview” for detailed information.
