Siemens 3RT2316-1AK60 SIRIUS 4-Pole Contactor, AC-1 18A, 110/120V AC Coil, Screw Terminal, Size S00 Original Brand New

Overview

The Siemens 3RT2316-1AK60 is a robust and reliable 4-pole SIRIUS 3RT23 contactor designed for switching weak or non-inductive loads, primarily in AC-1 applications. As part of the highly coordinated SIRIUS modular system, this compact S00 size contactor delivers exceptional performance and high contact reliability, making it an ideal choice for a wide range of industrial control and power distribution applications. It features a 110 V AC (50 Hz) / 120 V AC (60 Hz) coil and convenient screw terminals for secure wiring.

Key Features & Function

• 4-Pole Design: Suitable for switching multi-phase loads or for applications requiring robust isolation.
• AC-1 Rated (18 A @ 400 V / 40 °C): Optimized for resistive loads, heating applications, and general non-inductive switching.
• Flexible Coil Voltage: Operates with both 110 V AC (50 Hz) and 120 V AC (60 Hz) control supply, offering broad compatibility.
• Screw Terminals: Provides a secure and reliable connection method for main, auxiliary, and control circuits.
• Compact Size S00: Space-saving design for efficient panel layouts.
• High Contact Reliability: Engineered for consistent performance, especially for low-voltage/low-current auxiliary circuits (≤ 110 V, ≤ 100 mA).
• Integrated Auxiliary Contact: S00 size basic units include an integrated auxiliary contact for signaling and control purposes.
• Modular SIRIUS System Compatibility: Seamlessly integrates with other Siemens SIRIUS components like overload relays (3RU2, 3RB3) for comprehensive load feeder solutions.
• Global Standards Compliance: Adheres to essential international standards including IEC 60947-1, IEC 60947-4-1, and IEC 60947-5-1, ensuring worldwide usability.
• Climate-Resistant: Designed for reliable operation across various environmental conditions.

Benefit

• Enhanced System Reliability: High contact reliability and robust design minimize downtime and maintenance.
• Space Optimization: Compact S00 size allows for efficient use of panel space in electrical enclosures.
• Simplified Wiring: User-friendly screw terminals and front-panel terminals (for 3RT23 contactors) streamline installation.
• Versatile Application: Ideal for various switching tasks, including weak or non-inductive loads, grid disconnection, and transfer switching.
• Comprehensive Protection Option: Easily integrated with suitable short-circuit, overload, and overvoltage protection devices and accessories.
• Long Mechanical Service Life: Built for durability with high mechanical operating cycles.
• Easy Expansion: Can be expanded with additional auxiliary switches for increased control and signaling flexibility.
• Cost-Effective Maintenance: Solenoid coils are replaceable for 3RT23 contactors, extending product lifespan.

Application

The Siemens 3RT2316-1AK60 contactor is ideally suited for applications requiring reliable switching of non-motor load, such as:

• Heating Systems: Switching resistive heating elements.
• Lighting Circuits: Controlling large lighting banks.
• Capacitive Loads: Handling loads with a high inrush current in specific scenarios (ensure proper dimensioning).
• Power Factor Correction: Switching capacitor banks.
• General Industrial Control: Diverse control circuits for automation and machinery.
• Energy Management: Disconnecting loads or power generation plants from the grid.

Protection and Compatibility

Short-Circuit and Overload Protection: All connections should be protected using appropriate measures. For standalone contactor, refer to the technical product data sheet. For device combination (e.g., with overload relays or circuit breakers), consult the Digital/Configuration Manuals for load feeder. Auxiliary contacts require specific protection as detailed in the technical product data sheet. Control supply voltage connection should be protected in accordance with relevant standard and regulation, potentially using current-limiting power supplies or miniature circuit breaker.

Overvoltage Protection: 3RT23 contactors can be retrofitted with surge suppressors (RC elements, varistors, diodes) to dampen opening surges in the coil, ordered separately. Note that damping may increase contactor break times and auxiliary contact delay time.

Connection Method:

• Main Circuit: Screw terminals are standard.
• Auxiliary and Control Circuit: Screw terminal.

Electromagnetic Compatibility (EMC): The contactor meet requirement for environment category A. When used with frequency converters, observe configuration notes in the Equipment Manual.

Motor Protection: While primarily for AC-1, this contactor can be combined with Siemens 3RU2 thermal overload relay or 3RB3 electronic overload relay for overload protection if adapted for motor-driven load (AC-3 with specific version).

Operating Mechanism: This version features a conventional AC operating mechanism.

Accessories and Spare Part

A wide range of standardized accessories is available for all sizes of SIRIUS 3RT2 contactor, including:

• Auxiliary switches (front or side-mounted)
• Surge suppressor (RC element, varistor, diodes)
• Solid-state time-delayed auxiliary switches
• And more (refer to Siemens accessories catalog for SIRIUS 3RT2 contactor and 3RH2 contactor relay).
