Function

• Four-Pole Switching: Designed to open and close four electrical circuits simultaneously.
• Load Disconnection: Effectively disconnects resistive or weakly inductive loads and power generation plants from the grid.
• Transfer Switching: Facilitates seamless transitions between different power sources or loads.
• Integration into Control Systems: Acts as a critical switching element within automated control circuits, responding to signals from PLCs, sensors, or manual controls.

Protection and Safety:

The Siemens 3RT2316-1AF00 contactor is designed with comprehensive protection considerations:

• Short-Circuit and Overload Protection: Main and auxiliary connections require external protection. Refer to technical data sheets for detailed guidance on free-standing contactors or device combinations (e.g., with overload relays or circuit breakers).
• Control Supply Voltage Protection: Adherence to relevant standards for control panel configuration is crucial. The selection of a suitable power supply with current-limiting functions and appropriate protection devices (e.g., miniature circuit breakers) is recommended.
• Overvoltage Protection: The 3RT23 series allows for retrofitting with surge suppressors (RC elements, varistors, diodes) to dampen opening surges in the coil, protecting against overvoltage. Note that damping may increase break times.

Connection Methods:

• Main Circuit: Screw terminals are standard, offering reliable and straightforward wiring.
• Auxiliary and Control Circuit: Screw terminals ensure secure connections for control and auxiliary wiring.

Application

The Siemens 3RT.3 contactors are versatile and ideal for:

• Four-pole switching of weak or non-inductive loads (AC-1): Perfect for resistive heating elements, lighting circuits, and distribution applications.
• Disconnecting loads or power generation plants from the grid: Provides a safe and efficient means of isolation.
• Transfer switching: Enables seamless switching between different power sources or loads in various industrial setups.

Related Products & Accessories:
