Siemens 3RT2036-1AN20 Power Contactor 51A, 22kW, 220V AC, 3-Pole, Screw Terminal Original Brand New

Overview

The Siemens 3RT2036-1AN20 is a high-performance SIRIUS 3RT2 series power contactor designed for reliable switching of motors and other industrial loads. This robust 3-pole contactor is engineered to handle a rated current of 51A at an AC-3e/AC-3 operational rating and can manage a power output of up to 22 kW at 400 V. Featuring a 220 V AC control voltage (50/60 Hz), it is a versatile solution for a wide range of industrial applications.

Key Features

• High Power Rating: Capable of handling up to 22 kW (at 400 V) and 51A (AC-3e/AC-3), making it suitable for demanding motor control applications.
• Integrated Auxiliary Contacts: Includes one normally open (1 NO) and one normally closed (1 NC) auxiliary contact, providing flexibility for control circuit integration and status monitoring.
• Robust Screw Terminals: The secure and reliable screw terminals ensure a strong, vibration-resistant connection, simplifying installation and maintenance.
• Compact Size S2: The space-saving Size S2 design allows for efficient use of panel space without compromising on performance.
• AC Operation: Designed for a 220 V AC control voltage, compatible with standard industrial power supplies.
• Part of the SIRIUS Family: As a member of the Siemens SIRIUS 3RT2 series, it guarantees quality, reliability, and seamless integration with other Siemens control products.

Benefit

• Enhanced Reliability: Siemens’ trusted engineering ensures a long service life and consistent performance, reducing downtime and maintenance costs.
• Simplified Installation: Screw terminals and a compact design make the contactor easy to install and integrate into existing systems.
• Versatile Application: Ideal for motor switching, controlling resistive loads, and general-purpose industrial automation tasks.
• Safety and Durability: Built to withstand harsh industrial environments, ensuring safe and durable operation.
• Broad Compatibility: Seamlessly works with other Siemens SIRIUS components, including overload relays and circuit breakers, for a complete motor starter solution.

Function

The Siemens 3RT2036-1AN20 power contactor serves as a core component in motor starters and control systems. Its primary function is to electrically switch power circuits on and off. When the 220 V AC coil is energized, the main contacts close, allowing power to flow to the connected load (e.g., an electric motor). The auxiliary contacts simultaneously change state, providing feedback for control and interlocking circuits. This precise and reliable switching is essential for automated machinery and industrial processes.
