Product Positioning

The Siemens 3RT2035-1NB34 contactor is a SIRIUS 3RT2 series S2 size, 3-pole design, AC-3 rated current 41A, power 18.5kW (400V). The Siemens 3RT2035-1NB34 coil voltage is within a low voltage range of 20-33VAC/DC and is equipped with a surge suppressor, making it suitable for direct drive by PLC output modules. The auxiliary contacts are configured with 2NO+2NC, providing more complete circuit monitoring feedback.

Core Product Advantages and Features
Low voltage 20-33VAC/DC coil
It can be directly driven by a PLC output module or a low-voltage DC power supply, and is equipped with a surge suppressor.
2NO+2NC auxiliary contacts
It has one more monitoring contact point than the standard model, making it suitable for applications with high requirements for interlocking and status feedback.
