Siemens 3RT1364-6AP36 Contactor 4-Pole, 350A AC-1, 100-250V AC/DC, 2NO+2NC Original Brand New

Siemens 3RT1364-6AP36 Contactor – Robust 4-Pole Switching Solution

The Siemens 3RT1364-6AP36 is a high-performance SIRIUS S10 power contactor designed for reliable switching of resistive and slightly inductive loads (AC-1). With its robust 4-pole design and impressive 350A current rating at 400V (40 °C), this contactor is ideal for demanding industrial applications such as disconnecting loads, power generation plants, and transfer switching.

Equipped with a wide-range solid-state operating mechanism (100-250V AC/DC), the 3RT1364-6AP36 offers versatile control options and features integrated varistor coil damping for enhanced protection against overvoltage. It comes standard with two laterally mounted auxiliary switches (2 NO + 2 NC) for flexible control circuit integration. Connection is made easy with sturdy connection rails and screw terminals for the main circuit, and reliable screw terminals for auxiliary and control circuits.

Protection and Connection Information:

• Short-circuit and overload protection of main connections: Refer to the technical product data sheet for specific information on protecting a free-standing contactor. For device combinations with overload relays or circuit breakers, consult the Digital Configuration Manual for load feeders.
• Short-circuit and overload protection of auxiliary connections: Details are available in the technical product data sheet.
• Short-circuit and overload protection of control supply voltage: Adhere to relevant standards for control panel configuration. Consider power supplies with current-limiting functions and suitable protection devices like miniature or circuit breakers.
• Protection against overvoltage at the control supply voltage: 3RT13 contactors are factory-equipped with varistor coil damping. Note that damping increases break, opening, and closing delay times; refer to the Equipment Manual for detailed influence.

Connection Methods:

• Main Circuit (3RT136 contactors): Screw terminals with connecting bars suitable for cable lugs or flexible/rigid busbars. Can be fitted with broadened bus connectors (see accessories).
• Auxiliary and Control Circuit: Reliable screw terminals.

Electromagnetic Compatibility:

• The contactors meet the requirements for environment category A. When used with frequency converters, specific configuration notes in the Equipment Manual must be observed.

Contact Reliability of Auxiliary Contacts:

• For switching voltages $\le$ 110 V and currents $\le$ 100 mA, the auxiliary contacts of 3RT contactors ensure high contact reliability, particularly suitable for solid-state circuits with currents $\ge$ 1 mA at 17 V and higher.

Accessories and Spare Parts:

• For a comprehensive list of mountable accessories, refer to the overview graphic in the product documentation or the Accessories ordering data.
