Siemens SIRIUS 3RT2035-1NB34-3MA0 Power Contactor, 41A, 18.5 kW, 20-33V AC/DC, Size S2 Original Brand New

Overview: High-Performance Siemens SIRIUS 3RT2 Power Contactor

The Siemens SIRIUS 3RT2035-1NB34-3MA0 is a robust and compact 3-pole power contactor designed for switching motors and other loads up to 41 A (for AC-3e/AC-3 at 400V) or 18.5 kW. Part of the SIRIUS 3RT2 generation, this Size S2 contactor is known for its high-contact reliability, longevity, and exceptional switching capacity. It's engineered for efficient use in industrial motor control and automation applications.

Function

The Siemens 3RT2035-1NB34-3MA0 serves as a remotely or automatically operated switch for controlling power circuits, primarily for starting and stopping electric motors. The universal wide-range control voltage of 20-33V AC/DC simplifies engineering and inventory by accommodating various supply voltages, and the integrated varistor provides crucial coil surge suppression to protect the control electronics. The fixed (captive) auxiliary switch block (2 NO + 2 NC) ensures reliable signaling and interlocking functions.

Benefit

• Versatile Control: Wide-range AC/DC operation (20-33 V) with integrated varistor for maximum coil protection and flexibility.
• Space-Saving Design: Compact Size S2 footprint for efficient panel design and installation.
• High Reliability: Exceptional electrical and mechanical service life (10 million cycles) for reduced downtime and maintenance.
• Safety & Compliance: Built-in captive auxiliary switch block (2 NO + 2 NC) is ideal for safety applications, ensuring the auxiliary block cannot be removed.
• Easy Installation: Standardized screw terminals for secure and straightforward wiring of main and control circuits.

Application

This contactor is suitable for a wide range of industrial applications, including:

• Motor Control (Direct On Line/DOL starting)
• Switching resistive loads
• HVAC systems
• Pumps, Fans, and Conveyors
• General power switching in automation and control panels
