Siemens 3RT1065-2NP36 SIRIUS 3RT1 Power Contactor 265A, 132kW, 200-277V UC, Spring-Loaded Terminal Original Brand New

Overview

The Siemens 3RT1065-2NP36 is a high-performance, 3-pole SIRIUS 3RT1 power contactor designed for reliable switching of electric motors and other demanding loads up to 265 A in AC-3 and AC-3e applications. As part of the SIRIUS modular system, this robust device offers superior contact reliability and is engineered for use in challenging industrial environments. Its compact design features an electronic (UC) coil with a wide control voltage range of $200-277\text{ V}$ (AC/DC) and a dedicated $24\text{ V DC PLC input}$ for seamless integration into modern automation systems.

Benefits & Advantages

• Exceptional Reliability: Rated for both AC-3 and the higher efficiency AC-3e application categories, ensuring long-term motor switching performance.
• PLC Integration Ready: Features a dedicated $24\text{ V DC}$ input signal for direct, noise-immune connection to a PLC, simplifying control wiring.
• Maintenance-Free Wiring: Spring-loaded terminals on the control and auxiliary circuits provide fast, secure, and vibration-proof connections, reducing maintenance time.
• High Power Density: $265\text{ A}$ and $132\text{ kW}$ capacity in a compact S10 size, ideal for high-power applications with limited panel space.
• Flexible Control: Wide $200-277\text{ V}$ UC (Universal Control) coil allows operation from various AC or DC supply voltages, offering global versatility.

Function

The Siemens 3RT1065-2NP36 functions as an electrically operated switch for reliably controlling and protecting motors. Its primary role is to switch the main current to electric motors (up to $132\text{ kW}$), pumps, fans, and other industrial equipment. The built-in $2\text{ NO }+2\text{ NC}$ auxiliary contacts provide status feedback and control interlocking for complex circuits. The electronic coil drive ensures low-power consumption and minimizes holding power, which contributes to energy efficiency in the control cabinet.
