Siemens 3RT2036-1SP30 SIRIUS Power Contactor, 51A, 22kW, AC/DC Coil Original Brand New

Overview

The Siemens 3RT2036-1SP30 is a high-performance, 3-pole power contactor from the SIRIUS 3RT2 family, specifically designed for switching motors up to 22 kW at $400\text{ V}$ (Category AC-3e/AC-3). As part of the modular SIRIUS system, this size S2 contactor provides a compact, reliable, and future-proof solution for demanding industrial control and automation applications.

A key feature is the wide-range 175-280 V AC/DC coil with an integrated varistor for surge suppression, ensuring reliable operation across different supply voltages and enhanced protection for the coil. It is also a safety-rated device, featuring an F-PLC-IN connection for direct, simplified integration into safety circuits (e.g., SIL 2/PL c or SIL 3/PL e with redundant setup).

Benefit

• Reliable Motor Switching: Rated for $51\text{ A}$ (AC-3e/AC-3) and $22\text{ kW}$, ensuring robust performance for high-power motors.
• Safety Integration (F-PLC-IN): Simplifies wiring and meets modern safety standards by allowing direct connection to a Fail-Safe Digital Output (F-DQ) of a safety controller (e.g., SIMATIC F-PLC). This helps achieve safety levels up to SIL 2/PL c with a single contactor.
• Flexible Control: The wide-range $175-280\text{ V AC/DC}$ coil with integrated varistor provides maximum flexibility and protection against voltage spikes.
• Space-Saving Design: Part of the modular SIRIUS system, known for its compact size, enabling efficient panel design.
• High Quality & Global Compliance: Siemens SIRIUS products are climate-resistant, approved for worldwide use (IEC, UL/CSA), and compatible with high-efficiency IE3/IE4 motors.
• Easy Installation: Features proven screw terminals for a secure, robust connection in the main circuit.

Function

The Siemens 3RT2036-1SP30 functions as an electromechanical switching device primarily used for remote ON/OFF control of electrical motors and industrial loads.

1. Motor Control: It reliably switches the 3-phase current to electric motors (up to $22\text{ kW}$) in applications such as pumps, fans, conveyors, and compressors.
2. Safety Disconnection: The F-PLC-IN terminal allows the coil to be driven by a safety control signal, ensuring that the contactor can reliably and predictably open the main circuit contacts (safe state) upon a safety command (e.g., Emergency Stop).
3. Feedback/Interlocking: The integrated $1\text{ NC}$ auxiliary contact provides feedback on the main circuit’s status or can be used in interlocking circuits.
4. Surge Protection: The integrated varistor protects the coil from excessive voltage peaks when the coil is de-energized, prolonging its service life.
