Overview

The Siemens 3RT1364-6AR36 is part of the esteemed SIRIUS line of industrial controls, known for its quality and durability. This 4-pole contactor includes 2 normally open (NO) and 2 normally closed (NC) auxiliary contacts, providing essential feedback and control capabilities. Its solid-state operating mechanism with integrated coil damping (varistor) ensures reliable and quiet operation, while the connection rail/screw terminal options facilitate straightforward installation into existing systems.

Key Features & Benefit

• High Current Rating: Capable of switching up to 350 A at 400 V for AC-1 applications, ensuring robust performance for non-inductive loads.
• Versatile 4-Pole Configuration: Ideal for applications requiring multi-pole switching, such as three-phase systems with a neutral, or switching of multiple circuits.
• Wide Control Voltage Range: Operates reliably with a 250-500 V AC/DC control supply, offering flexibility in diverse power systems.
• Integrated Auxiliary Contacts: Features 2 NO + 2 NC auxiliary contacts for enhanced control, signaling, and interlocking functionalities.
• Robust Connection Options: Equipped with connecting bars for screw terminals, allowing secure connections via cable lugs or flexible/rigid busbars.
• Solid-State Operating Mechanism: Provides a wide operating range and includes integrated varistor damping to protect against overvoltage, extending coil lifespan.
• Compliance with Global Standards: Adheres to IEC 60947-1, IEC 60947-4-1, and IEC 60947-5-1 (auxiliary switches), ensuring international compatibility and safety.
• High Contact Reliability: Auxiliary contacts are optimized for low voltages (≤ 110 V) and currents (≤ 100 mA), making them suitable for solid-state circuits.
• Electromagnetic Compatibility (EMC): Fulfills requirements for environment category A, ensuring stable operation in industrial settings.

Function

• AC-1 Switching: Primarily designed for switching resistive or slightly inductive loads, such as heating elements, lighting systems, and distribution networks.
• Load Disconnection: Facilitates the safe and efficient disconnection of electrical loads or power generation plants from the main grid.
• Transfer Switching: Enables the seamless transfer between different power sources or circuits, enhancing system flexibility and reliability.
• Control and Signaling: Integrated auxiliary contacts provide feedback on the contactor’s status and can be used to control other components in a circuit.
• Overvoltage Protection: The integrated varistor within the solid-state operating mechanism effectively dampens opening surges, protecting the coil and extending its service life.

Protection and Safety:

The Siemens 3RT1364-6AR36 requires appropriate short-circuit and overload protection for all connections. For main connections, consult the technical product data sheet or digital configuration manuals for load feeders for guidance on standalone contactor protection or combinations with overload relays/circuit breakers. Auxiliary and control circuit connections also require suitable protection, considering relevant standards and regulations for control panel configuration. Overvoltage protection for the control supply voltage is inherent with the integrated varistor damping.

Connection Methods:

• Main Circuit: Features screw terminals with connecting bars, allowing for robust connections using cable lugs or flexible/rigid busbars.
• Auxiliary and Control Circuit: Utilizes reliable screw terminals for secure wiring.

Aplication

The Siemens 3RT1364-6AR36 contactor is perfectly suited for a wide array of industrial and commercial applications where the reliable switching of non-inductive loads is paramount, including:

• Heating and lighting circuits
• Capacitor banks
• Resistive loads in industrial ovens
• Isolation of power sources
• Generator changeover switches
• Backup power systems
• Any application requiring 4-pole switching of AC-1 rated loads.
