Protection and Safety:

The Siemens 3RT1364-6AF36 contactor requires appropriate short-circuit, overload, and overvoltage protection for all connections. Refer to the technical product data sheet and configuration manuals for detailed guidance on protecting main, auxiliary, and control supply voltage connections. Integrated varistor damping for the coil helps mitigate opening surges, but the influence on break and delay times should be considered.

Connection Methods:

• Main Circuit: Screw terminals with connecting bars, allowing connection via cable lugs or flexible/rigid busbars. Can be fitted with broadened bus connectors.
• Auxiliary and Control Circuit: Screw terminals.

Compatibility and Accessories:

For overload protection, the 3RT1364-6AF36 is compatible with 3RB2 electronic overload relays. While the operating mechanism and contacts are not replaceable for this model, a wide range of accessories for 3RT135 to 3RT137 contactors are available to expand functionality, including additional auxiliary switches.
