Siemens 3RT1055-2AM36 Power Contactor AC-3 150A, 75kW, 200-220V AC/DC Coil, Spring-Loaded Terminals Original Brand New

Overview

The Siemens 3RT1055-2AM36 is a robust and high-performance power contactor from the SIRIUS line, engineered for switching and controlling three-phase motors and other heavy-duty industrial loads. Rated for $150\text{ A}$ (AC-3e/AC-3) and $75\text{ kW}$ at $400\text{ V}$, this 3-pole contactor provides reliable operation in demanding environments.

It features a flexible 200-220 V AC/DC conventional drive coil and includes built-in $2\text{ NO }+2\text{ NC}$ auxiliary contacts for immediate integration into control circuits. The main circuit connection utilizes a busbar for high-current applications, while the control and auxiliary circuits use efficient, vibration-proof spring-loaded terminals, ensuring fast, reliable wiring.

Key Benefit

• Reliable High-Power Switching: Capable of handling $150\text{ A}$ (AC-3) and $75\text{ kW}$ at $400\text{ V}$, making it suitable for large motors and heavy industrial loads.
• Flexible Control Voltage: The 200-220 V control voltage accepts both AC and DC signals, simplifying inventory and application across different setups.
• Integrated Auxiliary Contacts: Comes standard with $2\text{ NO }+2\text{ NC}$ auxiliary contacts, reducing the need for external components and simplifying panel design.
• Time-Saving Wiring: Spring-loaded terminals for control and auxiliary circuits ensure secure, maintenance-free, and rapid wiring connections.
• Durable Design: Part of the trusted Siemens SIRIUS family, known for long mechanical and electrical lifespan.

Application

The Siemens 3RT1055-2AM36 contactor is ideal for:
