• Versatile Control Voltage: Wide-range 48-130V AC/DC solid-state operating mechanism simplifies design and reduces inventory.
• Integrated Auxiliary Contacts: Features 2 NO + 2 NC auxiliary contacts for versatile control circuit integration.
• Robust Construction: S10 frame size and durable design ensure long-term reliability in industrial environments.
• Enhanced Safety: Equipped with integrated varistor for coil damping, providing protection against overvoltage.
• Flexible Connection Options: Supports both connection rail and screw terminal wiring for ease of installation.
• Standards Compliant: Adheres to IEC 60947-1, IEC 60947-4-1, and IEC 60947-5-1, guaranteeing quality and safety.

Function

• Four-pole Switching (AC-1): Designed for efficient switching of weak or non-inductive loads.
• Grid Disconnection: Capable of safely disconnecting loads or power generation plants from the electrical grid.
• Transfer Switching: Ideal for applications requiring reliable transfer between different power sources.
• Control Circuit Integration: Auxiliary contacts facilitate integration into complex control and signaling circuits.

Protection and Safety:

The Siemens 3RT1363-6AF36 contactor emphasizes robust protection for all connections:

• Main Connections: Requires suitable short-circuit and overload protection (refer to technical product data sheet for free-standing contactors or Digital/Configuration Manuals for load feeder combinations).
• Auxiliary Connections: Protection information available in the technical product data sheet.
• Control Supply Voltage: Requires consideration of relevant standards for control panels and suitable protection devices (e.g., current-limiting power supplies, miniature or circuit breakers).
• Overvoltage Protection: Integrated varistor provides effective damping of opening surges in the coil, minimizing stress on the control circuit.

Connection Methods:

• Main Circuit: Utilizes screw terminals with connecting bars, allowing for cable lugs or flexible/rigid busbars. Specific 3RT136 and 3RT137 contactors can also be fitted with broadened bus connectors (accessories available).
• Auxiliary and Control Circuit: Reliable screw terminals ensure secure connections.

Motor Protection:

For overload protection when used in motor feeder applications, 3RB2 electronic overload relays can be directly mounted on the 3RT13 contactors.

Operating Mechanism:

The 3RT13 contactors feature a wide-range solid-state operating mechanism, enabling control with both 50/60 Hz AC and DC. This provides operational flexibility with defined operating ranges for both AC and DC control.

Auxiliary Contacts and Expansion:

The 3RT13 contactors are supplied with two pre-mounted laterally auxiliary switches. The basic units can be expanded with additional auxiliary switches, adhering to permissible configuration limits.

Accessories and Spare Parts:

A range of accessories and spare parts are available to enhance functionality and maintain the 3RT135 to 3RT137 contactors. Please refer to the overview graphic or Accessories ordering data for detailed information.
