Siemens 3RT1363-6AP36 Contactor 4-Pole, 275A AC-1, 100-250V AC/DC Control, S10 Frame Original Brand New

Overview

The Siemens 3RT1363-6AP36 is a robust 4-pole contactor from the SIRIUS 3RT13 series, specifically designed for switching non-inductive or weakly inductive loads (AC-1 applications). With a rated operational current of 275 A at 400 V and 40 °C, this S10 frame contactor is ideal for applications requiring high current switching capabilities, such as disconnecting loads, power generation plants from the grid, and transfer switching. Its wide-range solid-state operating mechanism supports both AC and DC control voltages from 100-250V, offering versatile integration into various control systems. Equipped with 2 NO (normally open) and 2 NC (normally closed) auxiliary contacts, and featuring a convenient connection rail/screw terminal system, the 3RT1363-6AP36 ensures reliable and flexible installation.

Key Features & Function

• High-Capacity 4-Pole Switching: Designed for AC-1 applications, capable of switching up to 275 A at 400 V (40 °C).
• Wide-Range Solid-State Operating Mechanism: Operates reliably with control supply voltages from 100-250V AC/DC, simplifying inventory and increasing application flexibility.
• Integrated Coil Damping (Varistor): Pre-equipped with a varistor for effective damping of opening surges in the coil, enhancing system stability and component lifespan.
• Built-in Auxiliary Contacts: Features 2 Normally Open (NO) and 2 Normally Closed (NC) auxiliary contacts, provided by two laterally mounted auxiliary switches, for comprehensive control and signaling.
• Robust Connection Options: Main circuit connections via screw terminals with connecting bars, allowing for cable lugs or flexible/rigid busbars. Auxiliary and control circuits utilize screw terminals.
• Electromagnetic Compatibility (EMC): Fulfills requirements for environment category A, ensuring reliable operation in industrial settings.
• High Contact Reliability: Auxiliary contacts are optimized for solid-state circuits, ensuring reliable switching even at low voltages (≥ 17V) and currents (≥ 1mA).
• Motor Protection Compatibility: Seamlessly integrates with 3RB2 electronic overload relays for comprehensive motor protection (when applicable for AC-3 switching of motor-driven loads, though this model is primarily AC-1).
• Standards Compliance: Conforms to IEC 60947-1, IEC 60947-4-1, and IEC 60947-5-1 (auxiliary switches), ensuring international safety and performance standards are met.
• Protection of Connections: Designed with considerations for short-circuit, overload, and overvoltage protection for all connections (main, auxiliary, and control supply), emphasizing system integrity.

Benefit

• Enhanced System Reliability: Integrated coil damping and robust construction contribute to a longer operational lifespan and reduced downtime.
• Flexible Application: Wide-range control voltage and 4-pole design make it suitable for a diverse range of non-inductive load switching and power distribution applications.
• Simplified Installation: User-friendly connection rail/screw terminal system facilitates quick and secure wiring.
• Improved Safety: Adherence to international standards and built-in protection considerations help ensure safe operation within your electrical systems.
• Space-Saving Design: Optimized S10 frame size for efficient panel layout.
• Cost-Effective Maintenance: While the operating mechanism and contacts are not replaceable, the overall robust design minimizes the need for frequent maintenance.
• Seamless Integration: Part of the comprehensive Siemens SIRIUS family, ensuring compatibility with other Siemens industrial control components.
