• Motor Protection Compatibility: Seamlessly integrates with 3RB2 electronic overload relays for comprehensive motor protection when used in motor feeder applications (though primarily for AC-1, it highlights system compatibility).
• Electromagnetic Compatibility (EMC): Fulfills requirements for environment category A, ensuring stable operation in various industrial settings.

Function

• Four-Pole Switching: Enables simultaneous switching of four circuits, ideal for multi-phase systems or complex load configurations.
• Load Disconnection: Effectively disconnects loads or power generation plants from the electrical grid, enhancing safety and control.
• Transfer Switching: Facilitates the seamless transfer between different power sources or circuits, crucial for redundant systems or changeover applications.
• Integrated Overvoltage Protection: The built-in varistor in the solid-state operating mechanism effectively dampens opening surges, protecting the coil and enhancing durability.
• Auxiliary Contact Functionality: The 2 NO + 2 NC auxiliary contacts provide crucial feedback on the contactor’s status and enable interlocking with other control components. These contacts are highly reliable, even at low voltages and currents (e.g., for solid-state circuits).

Standards & Protection:

The Siemens 3RT1363-6AR36 conforms to the following international standards:

• IEC 60947-1
• IEC 60947-4-1
• IEC 60947-5-1 (for auxiliary switches)

Protection of Connections: All connections should be protected against overload and short circuits.

• Main Connections: Refer to the technical product data sheet for free-standing contactor protection. For device combinations (contactor with overload relay or circuit breaker), consult the Digital Configuration Manual for load feeders or the Configuration Manual for load feeders.
• Auxiliary Connections: Information on auxiliary contact protection is available in the technical product data sheet.
• Control Supply Voltage Connections: Observe relevant standards for control panel configuration. Potential protection includes suitable power supplies with current-limiting functions. Load characteristics (inrush current, switch-on/holding power) and the use of miniature or circuit breakers for control circuits should be considered.
• Overvoltage Protection at Control Supply: 3RT13 contactors like the 3RT1363-6AR36 are factory-equipped with coil damping (varistor) for protection against opening surges.

Connection Methods:

• Main Circuit: Screw terminals with connecting bars for use with cable lugs, flexible busbars, or rigid busbars. Bus connectors can also be fitted.
• Auxiliary and Control Circuit: Secure screw terminals.

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

Contact Reliability of Auxiliary Contacts: The auxiliary contacts are engineered for high contact reliability, particularly suitable for switching voltages $\le$ 110V and currents $\le$ 100mA. They perform exceptionally well in solid-state circuits with currents $\ge$ 1mA at 17V and higher.

Motor Protection Compatibility: For overload protection, 3RB2 electronic overload relays can be mounted onto 3RT13 contactors.

Operating Mechanism: Features a wide-range solid-state operating mechanism controllable with both 50/60 Hz AC and DC.

• DC Control Operating Range: 0.8 x Us min to 1.1 x Us max
• AC Control Operating Range: 0.85 x Us min to 1.1 x Us max

Maintenance and Expandability:

• Operating Mechanism/Contacts: It is not possible to change the operating mechanism or contacts for 3RT13 contactors.
• Auxiliary Switches: The 3RT1363-6AR36 comes supplied with two laterally mounted auxiliary switches. While additional auxiliary switches can be mounted, the permissible configuration must be observed.
