Siemens 3RT2036-1AV60 SIRIUS Power Contactor, 51A, 22kW, 480V AC Coil, 3-Pole, Size S2, Screw Terminal Original Brand New

Overview 

The Siemens 3RT2036-1AV60 SIRIUS Power Contactor is a robust and reliable switching device designed for high-performance motor control and general-purpose switching applications in industrial environments. Part of the globally recognized SIRIUS 3RT2 series, this 3-pole contactor is engineered for performance up to 51 Amps (AC-3e/AC-3) and 22 kW at 400 V. It features an operating coil voltage of 480 V AC, 60 Hz, making it an ideal component for machinery and plant systems requiring a large frame size S2 contactor.

Benefit

• Reliable Motor Control: Rated for $22\text{ kW}/51\text{ A}$ (AC-3e/AC-3), ensuring secure and efficient switching of standard and high-efficiency motors.
• Space & Time Savings: Compact design (Size S2) within the SIRIUS modular system allows for high packing density and fast, simple wiring thanks to the integrated $1\text{ NO}+1\text{ NC}$ auxiliary contacts.
• Global Standard Compliance: SIRIUS products are approved for worldwide use (e.g., IEC, UL/CSA), making them suitable for international machine building and plant operation.
• Durable and Low-Maintenance: Features rugged construction and a proven screw terminal connection for a reliable and low-maintenance electrical connection, reducing downtime.
• Future-Proof Investment: IE3/IE4-ready for use with highly efficient motors, aligning your system with modern energy efficiency standards.

Function

The Siemens 3RT2036-1AV60 functions as a power contactor designed to switch electrical loads, primarily 3-phase AC motors. It operates by energizing its $480\text{ V AC, }60\text{ Hz}$ coil, which magnetically pulls in the main power contacts (3-pole) to complete the motor circuit. The integrated $1\text{ NO}$ and $1\text{ NC}$ auxiliary contacts provide a reliable interface for control and signalling circuits (e.g., for interlocking, feedback to a PLC, or indicating operational status).
