Siemens 3RT1363-6AE36 Contactor 4-Pole, AC-1, 275A Original Brand New

Siemens 3RT1363-6AE36 Contactor | High-Performance 4-Pole Switching for AC-1 Application

The Siemens 3RT1363-6AE36 is a robust and versatile 4-pole contactor designed for reliable switching of non-inductive or weakly inductive loads (AC-1). With a rated operational current of 275A at 400V and 40°C, this S10 frame size contactor is an ideal solution for a wide range of industrial power control applications, including disconnecting loads, controlling power generation plants, and transfer switching.

Overview

This high-performance Siemens 3RT13 contactor is engineered for durability and consistent operation in demanding environments. It features a wide-range solid-state operating mechanism, allowing for flexible control with both AC (24-60V AC) and DC (20-60V DC) supply voltages. The integrated coil damping (varistor) enhances coil protection and extends lifespan. Equipped with 2 normally open (NO) and 2 normally closed (NC) auxiliary contacts, the 3RT1363-6AE36 provides ample signaling and interlocking capabilities. Its sturdy design with connecting rails and screw terminals ensures secure and reliable connections for main, auxiliary, and control circuits.

Benefit

• Versatile Application: Optimized for 4-pole switching of AC-1 loads, perfect for non-inductive applications, load disconnection, and power transfer.
• Wide-Range Control Voltage: Flexible 24-60V AC and 20-60V DC solid-state operating mechanism simplifies inventory and design.
• Enhanced Reliability: Integrated varistor for coil damping protects against overvoltage, improving longevity.
• Comprehensive Auxiliary Contacts: 2 NO + 2 NC contacts provide essential feedback and control options for complex systems.
• Robust Construction: Designed to meet demanding industrial standards (IEC 60947 series) for long-term performance.
• Secure Connections: Screw terminals with connecting bars accommodate various cable types, including cable lugs and busbars.
• Easy Integration: Compatible with 3RB2 electronic overload relays for comprehensive motor protection.

Function

• Main Circuit Switching: Controls 4-pole AC-1 loads up to 275A at 400V.
• Load Disconnection: Safely disconnects loads from the electrical grid.
• Power Generation Plant Control: Facilitates the switching of power generation systems.
• Transfer Switching: Enables seamless transfer between different power sources.
• Auxiliary Signaling: Provides feedback on contactor status through 2 NO and 2 NC auxiliary contacts.
• Overvoltage Protection: Integrated varistor damps opening surges in the coil.

Protection & Compatibility:

• Short-Circuit & Overload Protection: All connections require suitable protection. Refer to technical product data sheet and configuration manuals for detailed guidance on main, auxiliary, and control circuit protection.
• Motor Protection: Can be combined with 3RB2 electronic overload relays for comprehensive motor overload protection.
• Overvoltage Protection (Control Supply): Integrated varistor provides damping. For 3RT23 contactors, retrofitting with RC elements, varistors, diodes, or diode assemblies is possible (ordered separately).
• Auxiliary Switch Expansion: Supplied with two laterally mounted auxiliary switches. Can be expanded with additional auxiliary switches (permissible configuration must be observed).

Connection Methods:

• Main Circuit: Screw terminals with connecting bars for easy connection of cables using cable lugs or flexible/rigid busbars. 3RT136 and 3RT137 contactors can also be fitted with broadened bus connectors.
• Auxiliary and Control Circuit: Reliable screw terminals for secure wiring.

Note: Damping increases break times of the contactor, opening delay times of NO contacts, and closing delay times of NC contacts. Refer to the Equipment Manual for detailed information on time response.
