• Wide Voltage Coil: Operates with both 110 V AC (50 Hz) and 120 V AC (60 Hz) control voltages, offering flexibility.
• Spring-Loaded Terminals: Ensures fast, secure, and vibration-resistant connections, reducing installation time and maintenance.
• Compact S00 Size: Optimizes panel space, allowing for more efficient designs.
• Robust Construction: Designed for continuous operation in demanding industrial environments.
• Integrated Auxiliary Contact: The 3RT231 series includes an integrated auxiliary contact for enhanced control circuit functionality.
• Standards Compliance: Adheres to international standards including IEC 60947-1, IEC 60947-4-1, and IEC 60947-5-1 (for auxiliary switches), ensuring safety and compatibility.

Application

The Siemens 3RT2316-2AK60 contactor is an excellent choice for a variety of applications, including:

• Four-pole switching of weak or non-inductive loads (AC-1)
• Disconnecting loads or power generation plants from the grid
• Transfer switching applications
• Control panels and automation systems
• Building management systems

Comprehensive Protection & Features:

• Connection Protection: All connections require appropriate short-circuit and overload protection. Refer to the technical data sheet for detailed guidance on protecting standalone contactors, and the Digital Configuration Manual for load feeders with overload relays or circuit breakers.
• Auxiliary & Control Circuit Protection: Guidance on protecting auxiliary and control circuit connections, including considerations for power supplies with current-limiting functions and suitable protection devices like miniature circuit breakers.
• Overvoltage Protection: The 3RT23 contactors can be retrofitted with surge suppressors (RC elements, varistors, diodes) to dampen opening surges in the coil, protecting sensitive control components.
• Connection Methods: Main circuit connections are via convenient spring-loaded terminals, while auxiliary and control circuits use screw terminals.
• Electromagnetic Compatibility (EMC): Fulfills requirements for environment category A.
• Contact Reliability: Auxiliary contacts are designed for high reliability, suitable for switching low voltages (≤ 110 V) and currents (≤ 100 mA), making them ideal for solid-state circuits.
• Motor Protection Integration: Compatible with Siemens 3RU2 thermal overload relays or 3RB3 electronic overload relays for comprehensive motor protection when used in appropriate applications (note: 3RT2316-2AK60 is primarily for AC-1, non-motor loads).
• Operating Mechanisms: Features a conventional AC operating mechanism for reliable performance.
• Accessories & Spare Parts: A range of accessories and spare parts are available, including surge suppressors and additional auxiliary switches, to customize and maintain your setup.
