Function

The Siemens 3RT2316-2AP60 contactor serves critical functions in industrial automation and power distribution:

• Switching Weak or Non-Inductive Loads: Efficiently controls resistive circuits, heating systems, and lighting.
• Disconnecting Loads from the Grid: Provides a reliable means to isolate electrical loads or power generation plants from the main supply.
• Transfer Switching: Facilitates the smooth transfer of power between different sources or circuits.
• Control Circuit Integration: Its operating mechanism enables precise control through external signals, making it a vital component in automated systems.
• Motor Protection Foundation: Acts as the switching element in combination with suitable overload relays for protecting motors against overcurrents.

Application

The 3RT2316-2AP60 contactor is ideal for a variety of applications, including:

• Heating and ventilation systems
• Lighting control
• Resistive load switching
• Power distribution panels
• Backup power systems (transfer switching)
• Industrial machinery control (for non-motor loads)
• Renewable energy systems (e.g., disconnecting solar arrays)

Protection & Safety Guidelines:

• Short-Circuit and Overload Protection of Main Connections: Refer to the technical product data sheet for information on protecting a free-standing contactor. For device combinations (contactor with overload relay or circuit breaker as motor feeder), consult the Digital Configuration Manual for load feeders.
• Short-Circuit and Overload Protection of Auxiliary Connections: See the technical product data sheet for detailed protection guidelines.
• Control Supply Voltage Protection: Adhere to relevant standards and regulations for control panel configuration. Consider power supplies with current-limiting functions and suitable protection devices (e.g., miniature or circuit breakers).
• Overvoltage Protection: 3RT23 contactors can be retrofitted with surge suppressors (RC elements, varistors, diodes) to dampen opening surges in the coil. These must be ordered separately. Note that damping increases break times and contact delay times.

Connection Methods:

• Main Circuit: The 3RT2316-2AP60 utilizes convenient spring-loaded terminals, including a plug-in design for device connectors, ensuring quick and reliable main circuit connections.
• Auxiliary and Control Circuit: Screw terminals provide secure connections for auxiliary and control wiring.

Motor Protection Compatibility:

For comprehensive motor protection, the 3RT2316-2AP60 contactor is compatible with:

• Siemens 3RU2 thermal overload relays
• Siemens 3RB3 electronic overload relays

These relays can be directly mounted onto the 3RT23 contactors to safeguard motors against overload conditions.

Contact Reliability:

For applications involving low voltages (≤ 110V) and low currents (≤ 100mA), the integrated auxiliary contacts of the 3RT23 contactors offer high contact reliability, making them suitable for solid-state circuits with currents ≥ 1mA at voltages of 17V and higher.
