Siemens 3RT2035-1AP64 SIRIUS Power Contactor, 41A, 18.5kW, AC-3/AC-3e, 220V/240V AC Coil, Screw Terminal, Size S2 Original Brand New

Overview: High-Performance SIRIUS Power Contactor

The Siemens 3RT2035-1AP64 is a robust, 3-pole SIRIUS power contactor engineered for efficient switching of motors and electrical. Part of the trusted Siemens SIRIUS modular system, this contactor offers a compact design, exceptional reliability, and seamless integration into motor feeder applications. Key features include a high rated operational current of  (AC-3e/AC-3), a versatile control coil, and convenient screw terminals for secure wiring.The inclusion of ⁷ auxiliary contacts and a removable auxiliary switch block provides advanced flexibility for control and monitoring circuits.

Benefit

• Exceptional Reliability: SIRIUS 3RT2 contactors are known for high contact reliability and robust construction, minimizing downtime in critical industrial processes.
• Easy Integration: As a component of the SIRIUS modular system, it is perfectly coordinated and pre-tested for combination with other SIRIUS switching and protection devices, simplifying the design and assembly of load feeders.
• Design Flexibility: The removable auxiliary switch block with contacts offers maximum flexibility for sophisticated control circuits and diagnostic signaling.
• IE3/IE4 Motor Ready: Optimized for use with modern, high-efficiency motors, ensuring future-proof control solutions.

Function

The 3RT2035-1AP64 Power Contactor functions as an electrically operated switch, primarily used to remotely start, stop, and reverse motors, as well as switch heating and lighting circuits. It establishes and interrupts the connection between the main power supply and the load.

1. Motor Switching: Safely controls 3-phase motors up to 18.5 kW by closing and opening the main power circuit.
2. Remote Control: The control coil enables remote or automatic activation/deactivation via a low-power signal from a (Programmable Logic Controller), control panel, or sensor.
3. Signaling: The integrated auxiliary contacts provide real-time feedback on the contactor’s status to the control system for interlocking and signaling purposes.
